Error handling is an important aspect of coding. When errors are treated properly, the programs operate smoothly and cause no annoying crashes for the end users. In Python, error handling happens with a try-except code construct. (If you come from another programming language, there is no such thing as a try-catch statement in Python.)
The try-except code works such that it tries to run an expression or a piece of code. If the run fails, Python proceeds to run the actions in an except block. If the run succeeds, no further action is taken.
As a quick example, let’s try to print an undefined value and show an error if it fails:try: print(x) except: print("Exception thrown. x does not exist.")
Output:Exception thrown. x does not exist.
Here the program tries to run the code inside the try block.
If (and when) it fails, the except block catches the exception and logs it into the console.
This is a definitive guide to handling errors in Python. You will learn how to use the try…except structure for dealing with exceptions in your code. Besides, you learn how to handle multiple exceptions and how to add finally and else blocks in the error-handling code to always run actions. All the theory is backed up with great and illustrative examples.
Let’s jump into it!What Is Error Handling in Coding?
Whenever you’re writing software code, there’s always a chance of something going wrong.
For example, if you expect a user to enter a number but they enter text instead, the program can crash if you haven’t prepared for such a faulty input.
Error handling is an important part of writing code that maintains the normal flow of your program without crashes and other annoyances.
If you’ve ever used a mobile app, and all of a sudden the app closes without warnings, there’s an unhandled error behind the scenes. It could be that the software code tries to read a value that doesn’t exist. Nonetheless, this is super annoying for the end users of your application, isn’t it?
When writing software code, you should always keep in mind what errors might occur to avoid the program causing annoying crashes.
As an example, if a Python function operates on the assumption that an input value is always an integer, it could lead to a crash if the input happens to be a string. To avoid crashes like this, you need to write the code such that it knows what to do if someone accidentally inputs a string instead of an integer.
This is where error handling helps. In Python, you can do error handling with a simple try-except code structure. The idea is to try to run a piece of code. If the trial fails, then the except block handles the error instead of letting the program crash.Try-Except Pattern in Python Error Handling
In Python, you can use try-except statements to handle errors and exceptions that might happen when you run code.
Errors that take place during the execution of a program are called exceptions. In Python, faulty expressions raise errors and exceptions that will crash your program if you don’t handle the exceptions properly.
For example, a classic example of an exception is when you try to access an undefined value or divide a number by 0.
An abrupt crash is not beneficial for you as a developer needless to mention for the end users of your applications.
This is where the built-in error-handling mechanism helps. Instead of letting your program crash, you handle the errors during runtime and the program execution continues.
The error handling pattern in Python consists of the following:
The try block. It runs a piece of code. If this piece of code fails, an exception is raised.
The except block. This block catches the possible error raised by the try block. Also, you can (and should) specify the type of error you’re expecting from the try block here.
The optional finally block runs a piece of code regardless of whether there were errors or not. This is an optional block of code you don’t need in the error handling scheme.
Here’s what a generic try except code structure looks like:try: except Exception:
This code is pretty intuitive to read. The try specifies a block of code that Python tries to run. If the run fails, the except block catches an exception and runs some code.Example
As an example, let’s run a try-except code to make sure the code doesn’t crash if a variable x is not defined:try: print(x) except: print("Exception thrown. x does not exist.")
Notice that even though this piece of code prevents it from crashing, the way it’s written right now is bad practice. This is because we don’t define the type of error we expect in the except block.Specify Error Type
To fix the earlier example, you need to know that when you’re accessing an undefined variable in Python, you should expect it to cause a NameError.
Now you can expect a potential NameError in the except block:try: print(x) except NameError: print("NameError: x is not defined.")
Output:NameError: x is not defined.
This not only makes the code more readable but also ensures you know what you’re doing. It’s much better to specify the type (or types) of error you might face instead of just catching a generic error.
Now, what if there is more than one exception that might occur? No problem. Python lets you define as many except blocks as needed.Multiple Exceptions in Python Error Handling
In Python, you can have multiple except blocks for handling different types of errors separately.try: except Exception1: except Exception2: except Exception3:
This is best demonstrated with an example.Example
Let’s create a script that divides two numbers by one another. When it comes to dividing numbers, there are two things that could go wrong:
One or both of the numbers are not defined.
The denominator is zero.
The first problem will raise a NameError. The second issue causes a ZeroDivisionError.
To prevent crashes caused by these two potential issues, you need to handle both types of errors in your code. To do this, let’s specify some try-except error-handling logic in the code.
In the try-except structure, you want to handle both exceptions separately. Thus, you need two except blocks for the different cases:try: result = x / y except ZeroDivisionError: print("Make sure no divisions by 0 are made.") except NameError: print("Make sure both numbers are defined.")
By the way, feel free to copy-paste the above code into your code editor and run the code to see what happens.
Now, because x and y are not defined, the program won’t crash thanks to the error handling you did. Instead, the program will print the message you specified that will be shown in case of a NameError:Make sure both numbers are defined
Now, let’s define x and y, but let’s make y zero:x = 10 y = 0 try: result = x / y except ZeroDivisionError: print("Make sure no divisions by 0 are made.") except NameError: print("Make sure both numbers are defined.")
Because dividing by 0 is mathematically not possible, this causes an error. But thanks to your careful error handling, this error doesn’t crash the program. Instead, it shows there was an error dividing by 0:Make sure no divisions by 0 are made.
Finally, let’s write the code in a way that there are no longer errors:x = 10 y = 5 try: result = x / y except ZeroDivisionError: print("Make sure no divisions by 0 are made.") except NameError: print("Make sure both numbers are defined.")
Now there is no error message. This means the program ran successfully because both x and y were defined and y was not 0.Finally Block in Python Error Handling
In Python, you can add a finally block in the try-except error handling code. The finally block is an optional block that runs regardless of whether there were errors or not.
For instance, let’s run a function that does error handling without the finally block:def run(): try: print(x) except: print("There was an error") return None print("Yay") run()
Output:There was an error
Notice that the function never prints “Yay” because it returns before.
To print the “Yay” part of the code, you need to add a finally block in the error handling structure. The finally block will run no matter what. Even if the function returns a value, the finally block will run and finish what it has to in the error handling code.def run(): try: print(x) except: print("There was an error") return None finally: print("Yay") run()
Output:There was an error Yay Else Block in Python Error Handling
You can also add an optional else block after except blocks in Python. The idea of an else block is to run code if there were no errors in the error handling sequence.
For example, let’s divide two numbers by one another, catch potential errors, and print a success message if no errors were thrown.x = 15 y = 5 try: print(x / y) except ZeroDivisionError: print("Make sure no divisions by 0 are made.") else: print("There were no errors.") Conclusion
In Python, there is no such thing as a try-catch statement. Instead, Python has its own version called try-except. The try-except code structure is used to deal with errors and exceptions.
Here is an example:try: print(x) except: print("x is not defined") finally: print("Process finished")
Output:x is not defined Process finished

Don’t let planning your Black Friday marketing strategy frustrate you. It’s easier than you think to stand out from the crowd on a busy sales day.
Here are 19 tried and tested marketing strategies to try for Black Friday!
Bonus: Learn how to sell more products on social media with our free Social Commerce 101 guide. Delight your customers and improve conversion rates.What is Black Friday?
Black Friday is the Friday following American Thanksgiving. It’s notorious for slashed prices in eCommerce and brick-and-mortar stores, causing a surge in consumer spending.
Black Friday typically kicks off the holiday shopping season. You might have heard stories of the pandemonium that brick-and-mortar stores face.
The term ‘Black Friday’ originated in Philadelphia in the 1950s. Police officers used it to describe the heavy, disruptive crowds that would flock to the city the day after Thanksgiving. Suburban shoppers and tourists would flock to the city before the infamous Army-Navy football game.
Later, retailers adopted Black Friday. They depended on holiday shopping to put them “back in the black” before the fiscal year ended. Back in the black just means earning profit instead of operating at a loss or “being in the red.”
Today, Black Friday has extended from brick-and-mortar stores to online sales, with eCommerce stores jumping on the holiday. It’s also extended its timeline. Now Black Friday isn’t just a day, it’s a weekend of sales between Black Friday and Cyber Monday.
eCommerce stores are reaping the benefits of online sales, even during a time when global buying habits shifted in an unpredictable market. In 2023, Shopify store owners collectively made a whopping $6.3 billion USD in sales globally between Black Friday and Cyber Monday, a 23% increase from 2023.
During this time, sales were attributed to 47 million unique shoppers who made a purchase from a Shopify merchant. These weren’t your classic bargain bin deals either. The average cart price was above $100 US!
These are opportunities that your business can get in on too. All you need is a stellar marketing strategy to help you stand out from the crowd.19 fool-proof Black Friday marketing strategies
There is no one-size-fits-all answer when it comes to Black Friday marketing strategies. You know your customers and what will work best for them. But, there are some tried and tested strategies that can help with your Black Friday marketing strategy.
Take a look below at these 19 fool-proof Black Friday marketing strategies.
By sharing previews of exclusive deals, countdown timers, and other engaging content, businesses can build anticipation and drive traffic to their stores on Black Friday. And social media is a great way to connect with customers and answer any questions they may have about your Black Friday sale.
2. Create a sense of urgency
To get customers excited about your sale items, write copy that conveys urgency. Creating a sense of urgency or scarcity in your Black Friday marketing encourages customers to take action.
One reason why creating a sense of urgency is important is that it helps to capture attention. In a busy inbox, for example, an email that stands out and creates a sense of urgency is more likely to be noticed than an email that doesn’t.
3. Email marketing campaign
Set up an email marketing campaign and watch your ROI grow, and grow, and grow. When you average it out, email drives an ROI of $36 for every dollar spent. That’s higher than any other channel.
4. Optimize your website for shoppers searching on Google
Black Friday is swollen with eCommerce sites vying for a spot on Google’s front page. To rank, you need to optimize your website for online shoppers.
One way to do this is to use keywords that shoppers are likely to use when searching for holiday deals. Do some keyword research, then float those words throughout your site. Make sure you sound natural and don’t fall into the habit of keyword stuffing.
In addition, you should also make sure that your website is mobile-friendly, as more and more people are using their phones to do their holiday shopping.
5. Install a chatbot on your website to make customer support easier
With more shoppers comes more customer support inquiries. You can’t avoid it. Consumers are going to be reaching out with FAQs about orders, shipping, and returns. You name it.
By installing a chatbot on your website, you can streamline and automate your customer support services. The chatbot can handle the easy FAQs, and when a customer support rep is needed, they can step in and take over the conversation. This process can remove the repetitive work weighing down your team and give them time back to focus on larger-scale issues.
6. Install a chatbot on your Shopify site, too
You want to make it as easy as possible for your customers to convert. So, if you use an eCommerce site like Shopify, consider installing a chatbot.
Shopify chatbots can pull data from your store to automate tasks. These include necessary customer communication, checking store inventory, performing returns, and encouraging sales.
During a rush like Black Friday, it’s important to give your customers the support they need. A chatbot helps you do so.
7. Use a chatbot to help shoppers find products faster
Besides automating customer service inquiries, AI chatbots like Heyday can also help with sales. If you find the right one, a chatbot can help shoppers to find the products they need quickly and easily.
This can work if you program your chatbot to ask shoppers a series of questions. From there, they can narrow down the search to a few specific items. Then, shoppers can either purchase the product online or find it in-store.
Chatbots can also provide personalized recommendations based on previous purchases. And, during the chaos that is Black Friday, you’ll want all the help you can get.

8. Offer long-time customers exclusive deals
People like to be acknowledged, especially when they have a relationship with your brand. Black Friday offers you a chance to show appreciation for loyal, long-time customers.
Offering exclusive deals and discounts to these customers is a smart marketing tactic that can help to build customer loyalty and drive repeat business. By showing your customers that you value their loyalty, you’ll encourage them to keep coming back on days that aren’t Black Friday.
9. Try selling directly on social media
People often use social media to research a product or look up a brand. Close to 1 in 2 people have reported looking up new brands, products or services on Instagram.
On Black Friday, everyone will be searching for deals and promotions. By selling directly on platforms like Instagram, you can put your products right in front of your target audience. Selling your products directly on the app means it’s even easier for your consumers to convert.
And you can reach a global audience on social media. People on Instagram, for example, expect to be marketed to. 90% of people follow a brand, after all.

A post shared by Instagram for Business (@instagramforbusiness)
Black Friday gives you an opportunity to reach new audiences on social media. By using hashtags, you can connect with people who are interested in Black Friday deals and help them find your products and services.
If you’re a retailer, you can use the hashtag #blackfridayshopping or #blackfridaydeals to reach people who are looking for bargains.
11. Follow up with customers after Black Friday
It’s great that you can sell a ton of products on Black Friday. But, a customer’s value to your brand grows over time. You want to turn those one-off purchasers into loyal, lifelong customers.
A study by Shopify notes that customer lifetime value is the lowest on holidays like Black Friday. It showed that for a whopping 64% of retailers, shoppers acquired during Black Friday or Cyber Monday have a lower lifetime value than shoppers acquired at any other time of the year.
Follow up by sending a quick thank-you email, a customer service survey, or by asking for feedback on their experience. You’ll be improving your customers’ experience, which can pay off in future dividends.
By taking the time to reach out to customers, you show that your brand truly values their business and that you’re committed to providing a positive customer experience.
12. Referral codes
You know that referral marketing can work wonders for your brand. It’s also effective in promoting Black Friday deals.
Send out referral codes to your email subscribers. Offer them gift cards or deeper discounts as incentives. Their referrals have the potential to pull in new customers with the added bonus of showing love to your loyal customers.
13. Minimum spend rewards
Offer minimum spend rewards on certain amounts. For example, if customers check out with a $100 cart, they could be eligible for free shipping.
Minimum spend rewards are a great way to increase your conversion rates and encourage customers to spend more money with a business. It can be even more effective if the rewards are tiered. For example, a customer who spends $50 might get a 10% discount, while a customer who spends $100 might get a 20% discount.
14. Give a free gift with purchase
People love feeling like they’ve been rewarded.
Giving your customers a free gift with their purchase will incentivize them to act. And they create a sense of goodwill that can keep customers coming back.
Of course, you want to make sure that you’re gifting something that your customers will actually want. It’s important to take your customer base into account when choosing what to give them.
15. Focus on your abandoned cart rates
Have you ever gone to do a bit of online window-shopping and moved to abandon your cart, only to be stopped short by a pop-up? Whether it’s an offer for a discount code or a survey about your shopping intentions, those pop-ups can be very annoying, which is kind of the point.
Pop-ups are meant to grab your attention and reduce abandoned cart rates. Give shoppers a chance to express their intentions or provide them with an incentive to complete their purchase. You’ll likely decrease your abandonment rate.
Be sure to get that pop-up to express your limited-time Black-Friday-only offer.
16. Make a gift guide
Oh, how we love Black Friday gift guides.
A gift guide is essentially a curated selection of your products, categorized in a way that makes it easy for shoppers to understand. For example, you could create a ‘For your fashionable friend’ guide that highlights unique clothing pieces you’re selling.
Gift guides help to promote specific products, drive traffic to your website or store, and generate excitement for your brand.
17. Have a social media contest
Offer a prize that your target audience wants and encourage people to take part in the contest and share it with their friends and followers. It works as social proof.
When one of your friends recommends a brand, you’re more likely to trust that brand. Get your followers to tag their friends or repost your content on their story for entries.
Schedule your contest and posts ahead of time with Hootsuite so you’re organized for the big day.
18. Get weird with it
Listen, you already know how murky the marketing swamp is going to be on Black Friday.
Retailers are going to be shouting about their low prices, hot deals, and fast delivery from every corner of the ring. If you want to stand out, you’ve got to grab attention. Don’t be afraid to try something new.
Deciem, for example, canceled Black Friday completely. They shut down their site and closed their stores as a way to reject the impulsive selling Black Friday is known for. Then, they announced they’re extending their sale through November.
19. Take a stance
Instead of promoting Black Friday sales, how can your company take a stance? Independent retailers around the world have started taking a stance against Black Friday and its overconsumption, whether that’s through donating profits, shutting down websites, or closing stores.
UK-based sustainable underwear brand Pantee turns off its website on Black Friday to the public and only allows access to those on its mailing list. This tactic is used to fight against the huge amount of unsustainable impulse buying driven by Black Friday promotions. They don’t do sales, and they don’t promote impulse buying.
Their message is to stop and think before you buy.

Imagine getting suited up for a meeting, and your camera isn’t working; you really don’t want the effort to go in vain. The Teams app has been around for quite some time. This has given us enough time to understand why the camera may not be working.
Camera issues can be difficult, however, difficult to understand. The issue can range from being extremely general to specific, so the user may find the diagnosis process a bit tedious.
In this article, we will be listing the causes of why your Teams camera may malfunction and how you can fix it. Stick around to get your camera working in no time!
Before you jump to the fixes, skim through the causes and determine the cause most relevant to you. You can find the fixes for each mentioned cause under this article.
Here is a list of causes for why your Teams camera may not be working:
Webcam Used by Other App
Outdated Teams App
Camera Driver Not Updated
Operating System Not Updated
You can test several solutions to fix the camera issue on Microsoft Teams. Below, we’ve listed both the general and specific solutions to the issue. After you’ve gone through the causes mentioned above, apply any of these fixes.
You can start your fix by running a simple test call to ensure that your camera hardware is working properly. If you determine that the issue is actually in your device, you can simply repair or replace your device. However, you can only use this feature if you own the paid desktop version of Microsoft Teams.
Follow these steps to run a test call in Microsoft Teams to check if your device camera is working properly:
Although the update is automatic for the desktop version of the Teams app; you need to update Teams on your mobile phones and tablets periodically. When you leave the Teams app outdated for a long time, it will fail to establish a connection with your device hardware.
You can visit Play Store to update your Teams app if you own an Android mobile or tablet. For iPhone or iPad users, update the Microsoft Teams app from App Store.
Drivers are essential to bridge the gap between hardware devices and the computer system. If you’re a Mac user, all your drivers are installed and updated automatically while you update your macOS. However, you can manually update drivers if you’re a Windows user.
You can update your camera driver from the device manager utility on your Window. Refer to the steps mentioned below to update camera drivers on Windows:
Your camera may not work because another application may be actively using your camera. This can be one of the more probable causes for why Teams may not be registering your video during a video conference call.
Make sure you close all windows that you believe may be using your camera. It’s best to close all applications running in the background. This applies to both the desktop application and mobile application versions of Teams.
Teams cannot access your camera if you haven’t granted the app the necessary permissions. To access devices like your camera and microphone, applications need special permissions for security reasons.
You can grant these permissions from the settings of your device. Using the Teams web version, you can find these permissions in the Site Settings. Refer to the steps mentioned below to grant camera access to the MS Teams application:
If you have more than one webcam connected to your PC, Teams could be actually using the other peripherals. You need to switch the webcam in use from the device settings in the Teams application.
Here are the steps you can refer to while switching camera devices in MS Teams:
When some files go missing or corrupt in a program, certain functions in the application malfunction. It is possible that the problem is that the program files for your camera do not work like it should on the Teams app.
You can fix this issue by repairing or resetting the MS Teams application. Repairing the application will scan through the program files for any missing or corrupted files. Windows will replace the corrupted files with a new, functioning one. Similarly, it will add the missing files.
Resetting the application will do the same, except it will also erase all data from the application. This eliminated the chances of any bugs that may be interfering with the features in the Teams app.
This feature is only available in Windows. If you own a Windows and wish to repair or reset your application, follow these steps:
When you leave your operating system outdated for long, it will severely impact the system. The system fails to maintain a connection between the software and the hardware. Your camera may not be working because your system may have failed to establish communication with your camera.
You need to update your operating system periodically. When you update your system, it not only maintains your system’s functioning but also protects it from any security vulnerabilities. Additionally, updates generally push resolutions to bugs from the previous update.
Follow these steps to update the operating system on your device:
If you are staring at a blank screen, your problem could be that DisplayPort is not detecting the monitor.
DisplayPort is a royalty-free digital display that supports 8k display at 120 Hz, GSync and Multi-stream Transport. Furthermore, it is backward compatible with other display interfaces, including VGA, DVI, and HDMI.
The other widely adopted display interface standard these days is HDMI. However, HDMI can only support 4k 30fps resolutions, and it doesn’t have support for GSync yet. Likewise, DP also supports Multi-stream Transport (MST), which allows you to connect multiple displays to a single DP port in your computer, whereas HDMI does not support this feature. Using DP over HDMI has started gaining traction in recent times, especially now that DisplayPort over USB C is becoming prevalent.
Sometimes, your DisplayPort connection to the monitor will not work due to bad cables, driver issues, etc. If you are having problems with DisplayPort not detecting your monitor, there are a few ways to troubleshoot this issue.
Incorrect Refresh Rate
Firstly, we will assume that your monitor is not broken. If you are having unable to connect your PC with your monitor or television using the DisplayPort connection, we have the following fixes that you can try:
The first fix you should try is restarting your display driver. This method takes just one quick second, and if it fixes the problem then you won’t have to bother with any other solutions.
To restart your display driver, press Win + Ctrl + Shift + B. Your screen will go black for just a second, then resume – indicating that your display driver has restarted. Make sure that your monitor and device are connected via DisplayPort and check if this resolved the issue.
Sometimes it will transpire that the connection was not properly secured at all, when we were sure that we plugged in the cables properly. Make sure you have not made the same mistake.
Check the connection at both the device and monitor ends. Full-sized DisplayPort plugs have a latch that you can secure into the port, make sure this latch is securely deployed.
Unplug the cable from both the device and the monitor.
Plug it back into both ends, making sure that they are connected securely.
Check whether your monitor is displaying now.
Modern monitors and televisions come with many different input sources. Especially for the DP, since it’s a royalty-free format, manufacturers typically include two or more DPs in their devices.
Make sure that you have selected the correct display source on your monitor. If you have selected a DisplayPort as your source, but your monitor has multiple DP inputs, cycle through all available options (typically listed as DP1, DP2, …) until your monitor is displaying your device’s output.
Refer to your monitor’s Device Manual to correctly identify the ports for further clarity on the matter.

Perhaps it’s the DP cable that is faulty? If your DP cable is broken, damaged, or not authentic, it might be unable to transmit signals to your monitor properly.
To check if this is the case, get a different DP cable and use it instead. Make sure that the cable is plugged in securely at both ends and check if your monitor can display your device’s output now.
If the pins in the DisplayPort jack that connects the cable are bent or broken on either the monitor or your device, then they won’t be able to make a proper connection. Inspect the ports in both devices to make sure that this is not the case.
If you find damaged or broken DP ports in either device, contact your device manufacturer or an authorized repair center to get this fixed.
Note: If your device is a laptop, then you can use your laptop’s display. Otherwise you will need a second working display or a different connection to make sure you can enact the steps listed in the fixes below.
Your monitor will be capable of displaying output at a frequency of certain frames a second, called the refresh rate. This is specific to your device’s make and model, which you can find in the packaging box or device manual.
If your computer is set to a refresh rate that is vastly different from the refresh rate that is supported by your monitor, this could lead to problems with the DisplayPort not detecting the monitor.
Refer to your monitor’s device manual and set the refresh rate to match it from within the Display Settings in Windows:
Check if your monitor is displaying now.
A faulty display driver could be causing the issue with your DisplayPort. Try uninstalling the display driver and reinstalling it to see if this resolves the issue.
An outdated display driver can also lead you to have problems with the DisplayPort connection. Try updating your display driver to see if this resolves the problem.
You can either let Windows select the most up-to-date driver or alternatively, you can download the latest driver from your graphics card manufacturer yourself and point to the location of the driver. Once this is done, restart your computer.
If your DisplayPort connection was working previously but it stopped working suddenly after a display driver update, then rolling back the update to display driver will probably fix the issue.
If you’ve been through all the fixes above without success, as a last ditch effort, you should contact the manufacturer of your monitor. The problem might be hardware-related that cannot be troubleshooted by users. You can also enlist the help of an authorized repair shop.
DisplayPort cables can and do go bad. Well, not in the sense of fruits left overnight on the counter-top bad, but over time if you move your device around, the bends in the DisplayPort cable can lead to fray and disconnection. Repeated plugging and unplugging can also lead to damage to pins that could spell doom to your DisplayPort cable.
If you are having any of the following problems, then you should check to see if your DP cable is bad:
If you experience any of these issues, you should physically inspect your DP cable and ports.
Up to an extent, you get what you pay for. Or in this case, you could end up not getting what you did not pay for. Cheap display cables generally come with a plethora of problems, including the cables not working outright. This usually happens with knock-off brands of questionable repute.
That said, do a bit of research and see what most DP cables from decent manufacturers cost. There is absolutely no need to splurge on something that is vastly more expensive than an average cable.
DisplayPort is compatible with the HDMI standards, so you can connect the DP output from your PC to the HDMI-in port of your monitor using an adapter.
