Working of localtime() Function in Perl with Examples

In this article, we will see the Perl time function known as localtime(), which is defined as a function for returning the time elements related to the date and time of the system or program. In Perl, date and time codes usually need a Perl module known as the DateTime module, which contains various combinations of representation of date and time where; this module uses a New Style calendar, which is known as a geographic calendar.

In Perl, to display date and time that has analyzed time of the current time zone which is done by converting the given expression of time into a set of time elements which is an array of time elements and contains at least 9 element in this array which includes the time and date of the current time zone such as second, minute, hour, day, month, year, day of the week, day of the year, isdst.

Now let us see syntax and examples of localtime() function:

Syntax:

Use DateTime; localtime();

In this, if there is no argument passed, then the localtime() function returns the current date and time of the timezone.

or with expression : locatime expr;

In this, we can write expr anything which can display result related to time elements only.

In the above syntax, both can be used where the first one displays the set of time elements having 9 different elements defining the time of time zone. Then the second syntax can display only those time elements which are specified as expression (expr) in the syntax as seen in the above syntax section.

Example #1 #!/usr/local/bin/perl use DateTime; print "Demonstration of localtime() function in Perl"; print "n"; print "n"; print "The use of localtime() function without any arguments "; print "n"; $sys_dt = localtime(); print "The date and time of the system of the timezone which is used is :"; print "n"; print $sys_dt; print "n"; print "The localtime() function to display particular format of date and time"; print "n"; @mon_name = qw( Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec ); @day_name = qw(Sun Mon Tue Wed Thu Fri Sat Sun); ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(); print "The current day name and month name is: "; print "n"; print "$mday $mon_name[$mon] "; print "$day_name[$wday] ";

Output:

In the above program, we can see we have first imported a Perl module for date and time as “use DateTime” so that we can use locatime() inbuilt function of Perl. In the above code, we are declaring a variable that stores the current date and time of the system where we are assigning this variable to store the value of the locatime() function and is displayed using the print command. In this, we have not passed any argument to the function, so it will just print the current day date and the current time in an hour, minutes and seconds along with the current year.

Then we are trying to use the localtime() function to display a particular date and time format, which we specify in print command where in the code we are printing only the current date with day and current month using localtime() function. Therefore we can use this function in both ways. We have written the month and day name in which format we want to display, and these are stored in the variables “mon_name” and “day_name” so that we can display in the same name which is defined here; we can also use full name to display here. The output can be seen in the above screenshot, which displays the system’s current date and time.

Example #2

Code:

#!/usr/local/bin/perl use DateTime; print "Demonstration of localtime() fucntion with argument in Perl"; print "n"; print "n"; $cur_dt = localtime(); print "The current date and time is as follows: "; print "n"; print $cur_dt; print "The elapsed time and date can be represented using time() function"; print "n"; $epoc = time(); $epoc = $epoc - 24 * 60 * 60; print "The elapsed time in seconds to display  yesterday's date and time is "; print "n"; print $epoc; print "n"; $cur_dt = localtime($epoc); print "The epoc passed as argument for displayng yesterday's date and time:"; print "n"; print $cur_dt;

Output:

In the above code, first, we import the “use DateTime” module for using the localtime() function. In this code, first, we have declared a variable to display the current date and time, which displays the current date and time of the system and then we are using another variable, “$epoc,” in which we are storing the number of seconds that are elapsed until the current day and time using time() function. Therefore we can see we have then passed this $epoc to the localtime() function, which displays yesterday’s date and time. The output for this code can be seen in the above screenshot.

Conclusion

In this article, we conclude that the localtime() function is a time function used to display the date and time of the time zone the system is using. This function returns the set or array of time elements which has 9 different elements of date and time such as hour, minutes, seconds, etc. In the article, we saw a simple example of using localtime() without argument and to display the particular date and time elements and also we saw another example where we are passing the elapsed time to display the elapsed date that is passed as an argument to the localtime() function.

How Does Qw Function In Perl With Syntax And Examples?

Introduction to Perl qw

Web development, programming languages, Software testing & others

Syntax

The Perl has some default set of operators that are being used for a set of operations to be performed after the script code execution. Likewise, the qw() is the operator and the function which has been used to split the sentence into each string by using some delimiters like single quotes, parentheses, etc. Mainly it returns the array of the elements as the list values.

@array = qw(some sentences based on the users input); Loop used for to iterate the values $variable (@array) { }

The above codes are the basic syntax for utilizing the qw() operators in the script. We can use any set of delimiters while we are passing the inputs to the method.

How does qw function in Perl?

The qw operator in Perl used to split the sentences that the user inputs may be the n number of lines they giving the input to the script. So it’s difficult to perform the operations in the script for storing and retrieving the datas from memory. Using delimiters, we can split the strings in various ways, but the string characters are split and equivalent to the corresponding user input values. The qw is the quote word that is related to the other operators like qq and q.

The user input datas are stored as the elements of the array because the list is the ordered set of collections using scalar type input variables and values, and the arrays are the variables that held to the lists in the Perl codes. We can extract every array element in the string datatype values; it may be out of scope in the list using some delimiters like space, commas, quotes, backslash, forward slash, etc. These are some default delimiters available in the Perl scripts. For each Perl script functions, the operators are assigned to the variable values using some default loops; the values are iterated and displayed on the output screens.

The user input as sometimes list formats the list is the set of sequence scalar values it can be used and delimiters the datas using parenthesis and comma operators. By using these operators, the list is to be constructed and also each value of the list is known as the list elements; these elements are to be some sorting type of ordered with indexed values. These values are to be set and allotted with some storage positions in the memory. Quote function uses the embedded type of whitespaces. If we use non-alphanumeric characters in the strings, we use the q/ and q// operators as delimiters; the list is any type which they have used in the elements.

Each set of list elements are stored at a specific position in the memory list. The range set of operators is performed using these functions not only for the strings; by using the qw; we can avoid the quote marks. We entered the datas less in the list we use a punctuation set of characters as the delimiters in the array variables. Whenever the delimiters used, the opening and closing parenthesis are must be the same in the array elements.

Examples of Perl qw

Here are the following examples mention below

Example #1 #!/usr/bin/perl use warnings; use strict; my @months = qw(Dec Nov Oct Aug July June May Apr Mar Feb Jan); $months[0] = 'June'; @months[1..6] = qw(December November October August July June May April March February January); print("@months","n"); my @var1 = sort @var; print("@var1","n"); my @first = qw(Welcome To My DOmain kdjhv hkdsjbjkfw     qwdkhefj90898 iwidhfkjbdfkdh   qwdjehfkdbj o                                   qhkwdbjfqwljdk    qwhkdbjvjn wqdljkhfjb    qwkjefdb   qwjkdhbf qwkdhfjbdf wqihkewfj 2oiewhlfkj iwqehwfgkjdb eihwfjfb ewihfugejdv  owhefb oiewhkbd  qwdhksjb qiowhew); my @second = sort @first; print("@second","n");

Output:

Example #2

Code:

#!/usr/bin/perl use warnings; use strict; my @expn=(); @expn = ('12', '763', '127344', '73784','629387867', '23784', '82347', '346c', '73', '387', '83', '8374r', '83', '467', '837', '874', '93897', '3748', '784', '93'); @expn = qw/12 763 127344 73784 629387867 23784 82347 346c 73 387 83 8374r 83 467 837 874 93897 3748 784 93/; my %vars = (); while (my ($keys, $values) = each %vars) { }

Output:

Example #3

Code:

#!/usr/local/bin/perl use strict; use warnings; my %example = (); %example = qw( 1 718253 6253 welcome To My Domain kjagdsvj j kqwdbvwjkdfd lwjekfjwekjlfwekljf helfkjvwekjfhkwerhrfj kwejf kehgf wekrjg ewkhrjgh ewiiurh erjh 298 98 9028 928 cguh 2983 2763 jqwhevg 728365 28937 wdghe 298376 sdhgc 2837we sjdhg 3847 siudy 23847re6 sdedf 237eyr wdjh 23847r ewuy23  3847 weduf233 384 sjd qiwh 987 kjh 978 kjwqegh 786 ); foreach my $var (sort keys %example) { }

Output:

In the above three examples, we used the qw() operator with different scenarios; we can use the operator using some methods like sorting, unsorting, slicing the elements in the both array and list of the script.

Conclusion

In Perl scripts, we used different operators, keywords, variables, and functions to create the applications using text manipulations, data securities, other IT, System-related issues, Web development, and network programming concepts. In that programming concept, this operator is must be concatenated and split the huge datas using some delimiters technique.

How Does Unpack Function Work In Perl?

Introduction to Perl unpack

Web development, programming languages, Software testing & others

Syntax:

The unpack is one of the functions that can be converted or transform the binary data type values into the user-defined data type templates with the help of representations that are related to the perl script functions, keywords, and other built-in syntax. The below codes are the basic syntax for creating and using the unpack function in the perl scripts.

#!/usr/bin/perl -w $vars= pack(""); @vars1=unpack("$vars");

—some Perl script logic codes depend upon the requirement—

How does unpack function work in Perl?

Generally, the perl script does not have to access the memory randomly. It has some structure and represents the same with some translators like a pack and unpack() functions. It has some default representations. It can be called a template like that if we use unpack() function; it seems like the opposite process of the pack() function. The binary data with some specific structures has its own reference of each value stored in the memory. So the pack function contains the specific format for listing out the values and packed or converted into the character strings but unpacks takes only the format with the character strings with some breaks to the strings with the specified formats and assigned with the variables in the script.

Examples

Let us discuss examples of Perl unpack.

Example #1

Code:

#!/usr/bin/perl -w $vars = pack("siva", 7849367); print "Welcome To My Domain $varsn"; $vars = pack( "" ); print "Have a Nice Day $varsn"; $vars = pack( "siva", 6354, "I", 6858 ); print "Welcome User please find your packed values $varsn"; @vars1 = unpack( "siva", "$vars" ); print "Thank You User your first Input user values $vars1[0]n"; print "Thank You User your second Input user values $vars1[1]n"; print "Thank You User your third Input user values $vars1[2]n"; print "Thank You User your first Input user values $vars1[3]n";

Output:

In the above example, we used the pack() and unpack() function at the time, and also we can use the variable like $vars. We assigned the value to the specific variable and used the pack and unpack() function based on their needs.

Example #2

Code:

#! perl -w use strict; sub exa { shift; } sub demo1 { unpack "i*", shift; } sub demo2 { unpack "V*", shift; } sub demo3 { unpack "I*", shift; } sub demo4 { unpack "a*", shift; } sub demo5 { unpack "b*", shift; } sub demo6 { unpack "c*", shift; } sub demo7 { unpack "d*", shift; } sub demo8 { unpack "h*", shift; } sub demo9 { unpack "l*", shift; } sub demo10 { unpack "n*", shift; } sub finsa{ my $vars= shift; my $vars1 = "Welcome To My DOmain wdejfh bwefvhd gdv gv jgfjw egf wkejg jerfg jewrgf ekjwrhw kjejhrw kjergkw j ehgw ejhrgke jrgf kjergk ejhrgfkw ejhrge jhrgfkweh jrk ehjkw jerhke jh ekhrj hg"; my $vars2 = "983465 ifsdg8 shdfgh he sdjsb khbwdsh 9876asnbd 87 hjg 90 jh999 jhjhj g89 7987987 hjh j j979 8jkhj 9jh egdf gh8888 wgefh w8 hh98878 878 87 7 79 7 778 78 89 9 98 98 98 98 98 9 9 "; if ($vars3 =~ /^$vars2/i) { print "Welcome Usersn"; } else { } } finsa &exa; finsa &demo1; finsa &demo2; finsa &demo3; finsa &demo4; finsa &demo5; finsa &demo6; finsa &demo7; finsa &demo8; finsa &demo9; finsa &demo10;

Output:

Example #3

Code:

#!/usr/bin/perl -w $vars = pack("B*", 192, 168,42, 76); print "Welcome To My Domain $varsn"; @vars1 = unpack("B*", "welcomen"); print "Array $vars1[0]n";

Output:

In the final example, we used the basic pack() and unpack() functions in the ip numbers. Basically, with the help of ‘.” Operator or symbol, we can split the numbers and set it as the system’s ip address.

Conclusion

Finally, we used Perl as default control basic structures, functions, user input, and output operations. These are the concepts that are held through the script for creating the task depending upon the user’s requirement.

How Python Eval Function Work With Examples

Introduction to Python eval()

Web development, programming languages, Software testing & others

Syntax:

eval(expression, globals=None, locals=None)

Explanation:

Eval() function usually needs 3 parameters, but the 2nd and 3rd parameter terms are optional/not much important than the 1st parameter. The 3 parameters are expression, globals, and locals.

Expression parameter: This is the string that is as parsed and also evaluated as the Python expression.

Globals parameter ( dictionary parameter ): This parameter is a dictionary, and this parameter is also optional. Nothing happens even if we don’t specify this parameter in the eval() function.

Locals parameter ( Mapping Object ): This locals parameter is an object which is mapping… The dict or dictionary of the globals parameter is the best and standard mapping type in the Python Programming Language commonly.

How Python Eval Function Work with Examples

Eval() function/method will returns the value/result after evaluating the expression. eval function works by parsing the string value, and that string value also be evaluated as the python expression.

Example #1

At each and every IF statements, if the IF condition is False, then the interpreter of python goes to the ELSE condition’s statements, and the programming inside of it will be printed/interpreted etc.. all at a time, but the program inside of the ELSE condition is also be interpreted every line one by one.

Code:

x = 10 print(eval('x')) print(eval('x+10')) print(eval('x*x')) print(eval('x*x*x')) if(x%2==0): print('X is even number') if(x%2!=0): if(x%3!=0): if(x%5!=0): if(x%7!=0): print(eval('x')) print('is a prime number') else: print ('x is not prime number') else: print('x is not prime number') else: print('x is not prime number') else: print('x is not prime number')

Output:

Example #2

Now we enter the try, except concept. These are just like the IF and ELSE condition. If the “try” has correct parameters, then try to run properly and exits from the program, or else the except concept comes into the picture. Try, except concept will be very helpful to handle errors and usage of the eval() function/functions. Statements that are in the try will print the eval() function, which has math functions “square root” and the power of x and y values which are about to declare manually by the user. If the input doesn’t contain any input as needed with the mentioned math functions, the result will be printed, and the loop once again runs and asks again for the input, or else you can just enter and go the except concept. There you will print the ext1 value, and the interpreter breaks out and comes out from the except concept. Then the print statement will print “Now it is Done” like that.

Code:

from math import * for lm in range(1, 3): func1 = input("Enter the Math Function which are mentioned below to Evaluate.nFunctions Allowed are: 1. square_root(x) and 2. power(x,y):n") try: print(eval(func1, {'square_root': sqrt, 'power': pow})) except Exception as ex1: print(ex1) break print('Now it is Done')

Output:

The Seq() Function In R: A Complete Guide (With Examples)

Dealing with number sequences in data science is common. Having the tools to easily produce sequences of numbers of different lengths, stepsizes, and start/end values is crucial. This way you can avoid having to write loops to produce number sequences over and over again. In R, you can use the built-in seq() function to create number sequences easily.

x <- seq(10) # 1,2,3,4,5,6,7,8,9,10

This is a comprehensive guide to the seq() function in R.

You will learn the syntax among the different optional parameters. All the theory is backed up by great and illustrative examples that cover each of the seq() function parameters.

What Is the seq() Function in R?

In R, you can generate a sequence of numbers with the built-in seq() function. The seq() function allows you to control the start and end values of the sequence as well as the desired length and step size.

Before taking a look at examples, let’s see what the complete syntax of the seq() function looks like.

Syntax

Typically, you see the seq() function being used with a single argument like this:

x <- seq(10)

This produces a sequence of numbers from 1 to 10.

But the full syntax of the seq() function in R is:

seq(from=1, to=1, by=1, length.out=NULL, along.with=NULL)

Where:

from is the starting value of the sequence.

to is the end value of the sequence.

by is the “jump length” by which the values are incremented every step.

chúng tôi is the desired sequence length.

along.with is the desired sequence length that matches the length of another data object.

In the examples section, you will learn how to use each of these parameters in the seq() function call.

Examples of the seq() Function in R

Let’s take a look at 5 different examples of the seq() function in R that covers all the different parameters.

Example 1: The ‘from’ Parameter

The most basic way to call the seq() function in R is by giving it a single parameter, that is, the end value of the sequence. When you do this, the default start value of the sequence is 1 as well as the default step size.

For example, let’s create a sequence of numbers from 1 to 10:

x <- seq(10) x

Output:

[1] 1 2 3 4 5 6 7 8 9 10 Example 2: The ‘from’ and ‘to’ Parameters

Not always do you want the sequence to start from 1. In this case, you can specify both the start and the end values for the sequence by specifying the from and to parameters in the seq() function call.

For example, let’s produce a sequence of numbers from 5 to 10:

x <- seq(from=5, to=10) x

Output:

[1] 5 6 7 8 9 10 Example 3: The ‘by’ Parameter

Thus far you’ve seen examples where the stepsize is 1, that is, consecutive numbers are incremented by 1 in the sequence. But if you want to produce sequences with stepsizes other than 1, you need to specify the optional by argument in the seq() call.

For example, let’s create a sequence of numbers from 5 to 100 with a stepsize of 10:

x <- seq(from=5, to=100, by=10) x

Output:

[1] 5 15 25 35 45 55 65 75 85 95 Example 4: The ‘length.out’ Parameter

Sometimes it’s useful to specify a sequence of numbers in a range with a fixed length. This way you can uniformly distribute values of a certain length to a sequence of predetermined length.

For example, let’s generate a sequence of values between 0 and 10 and set the desired length of the sequence at 4:

x <- seq(from=0, to=10, length.out=4) x

Output:

[1] 0.000000 3.333333 6.666667 10.000000

The seq() function calculates the numbers such that they are evenly distributed across the range.

Example 5: The ‘along.with’ Parameter

When dealing with multiple sequences of numbers, you sometimes might want to generate a new sequence such that it matches the length of another one.

Of course, you could set the optional out.length variable to the length of the desired sequence. But if the length needs to match with another sequence, it’s safer to specify the optional along.with parameter. This way the code is more consistent and the intent is clearer.

For example:

y <- c(0.1, 1.5, 2.9, 4.6) x <- seq(from=0, to=10, along.with=y) x

Output:

[1] 0.000000 3.333333 6.666667 10.000000 Summary

Today you learned how to use the built-in seq() function in R.

To recap, the seq() function produces a sequence of numbers from a start value to the end. You can use the seq() function to produce sequences with the desired length, stepsize, and start/end values.

Working And Examples Of If Statement In React

Introduction to React If

For any coder or a Developer, applying If statements is one of the most basic skills they need. If statements are used to make behavioral changes in the product. For example, If a person’s age is above 18, he can drive a vehicle else; he is not eligible for driving. It also supports If statements. It comes under conditional rendering and is used just the way it is used in JavaScript. If a statement is used to match the condition, let the User Interface reaction be the basis of the user’s action. This article has covered some examples to help you understand how the If statement can be used to React to fulfill our requirements.

Syntax

Working of If statement in React

As we can see in the above syntax of the If statement in React, Here, the age which the user provides is matched against the driving age, and if the user’s age fulfills the condition, then there is a success message; otherwise, the user is not eligible for driving. This was a basic example to understand the working of the If statement in React.

Examples of React If

Different examples are mentioned below:

Example #1 – Basic Example of React If

index.js (inside component folder)

import React from "react"; return ( ); }; return ( ); };

index.js (main file)

import React from "react"; import ReactDOM from "react-dom"; import { Button , Form } from "./components"; import "./styles.css"; class App extends React.Component { constructor(props) { super(props); this.state = { showForm: false }; } this.setState({ showForm: !this.state.showForm }); }; render() { let RenderedComponent; if (this.state.showForm) { } else { } } } const rootElement = document.getElementById("root");
