Definition of sprintf in Python

The sprintf is a function to display the output of the given input using a python programming language.

The sprintf is a print function to shows the output of the format strings in the python language.

It is a coding element to assigns the “f get” method and displays string format output.

The sprintf is a print element to contain string – buffer data of the application and display in the string format using python technology.

The sprintf is a function similar to print, vprint for display buffer output hustle-free.

The python programming language is using the sprintf function to declare argument and constructor elements.

It is an output function to displays all data types like string and array elements.

Syntax:

The sprintf python works with different data types, lengths of the data, and width.

It has used the percentage sign (%) before the type of the data.

The basic syntax of a sprintf shows below.

% [FLAG WIDTH. (DOT) PRECISION] TYPE

The sprintf python is using the “print” keyword to display output.

print("% [flag width . (dot) precision] type" % (value or object))

The sprintf is used precision and type depends on the data type of the variable. This syntax helps to assign a signed decimal number. The length value of a decimal is 2.

%2d

This syntax helps to assign a binary number. The length value of binary is 4.

%4b

This syntax helps to assign a floating number. The length value of a decimal is 2.1.

%2.1f or %2.1F

This syntax helps to assign ASCII values.

%c

This syntax helps to assign unsigned decimal values.

%u

This syntax helps to assign an octal number.

%o

This syntax helps to assign a hexadecimal number.

%x OR %X

This syntax helps to assign scientific notation of a lowercase.

%e

This syntax helps to assign scientific notation of an uppercase.

%E

This syntax helps to return the type of data format.

%%type How does sprintf work in Python?

Download python software from the respective website. Create a page with the dot (.) py extension. The file name is the “function.py” to write a python program. Create a variable with initializing the required data type value.

Varble_name = 34

Use the print keyword for the string format of the sprint python.

print (write sprint format)

Use percentage sign to return value.

print (" text : %d ")

Display length of the variable or value before data type.

print (" text : %2d ")

Display the type of the variable value in the format helping of the sprint. Use parameter of the percentage sign to end of the sprintf function end. Add variable to interconnect return function and application data.

print (" text : %2d " % (Varble_name))

Use direct value in sprint function to display decimal value.

print("decimal number : %2d " % (7))

Use float type with sprintf formatted value in the return function.

print("Float number : %5.2f" % ( 23.11))

Combine the working procedure of the sprintf python to better understanding.

x = 34 print ("decimal number : %2d " % (x)) print ("decimal number : %2d " % (7)) print ("Float number : %5.2f" % ( 23.11)) Examples Example #1 – Basic

Code:

e_var = 34 print ("decimal number: %2d " % (e_var)) print ("decimal number: %2d " % (7)) print ("Float number: %5.2f" % ( 23.11)) print ("Float number: %5.4f" % (e_var)) print ("Octal number: %5o" % (e_var)) print ("Octal number: %3o" % (42))

Output:

Example #2 – With different types

Code:

e_var = 341234673 print ("decimal number: %d " % (e_var)) print ("Float number: %f" % (e_var)) print ("Float number: %F" % (e_var)) print ("unsigned decimal number: %u" % (e_var)) print ("Octal number: %o" % (e_var)) print ("first string value: %s" % (e_var)) print ("second string value: %s" % ("string data")) print ("first hexadecimal value: %x" % (e_var)) print ("second hexadecimal value: %X" % (e_var)) print ("ASCII value: %c" % ("A")) print ("lowercase scientific notation: %e" % (e_var)) print ("uppercase scientific notation: %E" % (e_var)) print ("first value: %g" % (e_var)) print ("second value: %G" % (e_var))

Output:

Example #3 – With positive and negative value e_var = 341234673 f_var = -341234673 print ("decimal number: %d " % (e_var)) print ("decimal number: %d n " % (f_var)) print ("unsigned decimal number: %u" % (e_var)) print ("unsigned decimal number: %u n" % (f_var)) print ("Octal number: %o" % (e_var)) print ("Octal number: %o n" % (f_var)) print ("first hexadecimal value: %x " % (e_var)) print ("first hexadecimal value: %x n" % (f_var)) print ("second hexadecimal value: %X " % (e_var)) print ("second hexadecimal value: %X n" % (f_var)) print ("lowercase scientific notation: %e" % (e_var)) print ("lowercase scientific notation: %e n" % (f_var)) print ("uppercase scientific notation: %E" % (e_var)) print ("uppercase scientific notation: %E n" % (f_var)) print ("first value: %g" % (e_var)) print ("second value: %G" % (f_var))

Output:

How Does Redirect Work In Javascript?

Introduction to JavaScript Redirect

JavaScript redirect is the process of sending requests form one page to another page through accessing the corresponding URL (Unified Resource Locator). Redirecting URL is also used for sending the user from one URL to another URL. location is the function used in JavaScript to redirect at the specific URL.

Real Time Scenario:

Advantage:

We can add more information within a single page by this URL redirect.

Pre-requisites:

Basic HTML

Basic JavaScript

How does Redirect Work in JavaScript?

JavaScript redirect is working based on different types of redirect methods. Each redirect has its own specification.

Syntax:

location = "URL";

Description: It will set the new location for the current window.

location.href = "URL";

Description: It will set the new href for the current window.

location.assign("URL");

Description: It will assign the new URL to the current window.

location.replace("URL");

Description: It will replace the current window location with a new location.

location = "URL";

Description: It will just set the current window location itself.

location = "URL";

Description: It will set the topmost window location with a current window location.

Note: The difference between href and replace method is replace() method removes the URL of the current document from the document history, means it is not possible to use the “back” button for navigating to the original document.

Examples of JavaScript Redirect

Given below are the examples mentioned:

Example #1

Window location URL.

h1 { text-align: center; color: green; } p { font-size: 28px; border: solid 3px blue; color: maroon; } page to other page through accessing the corresponding URL (Unified Resource Locator). Redirecting URL is also used for sending the user from one URL to another URL. Window.location is the function used in website, while I am reading, I have some doubts with specific topics. Instead of providing everything there itself, we can simply summarize the topic and in between doubtable points can be provide with URL window.location = url;

Output:

After few milliseconds (1sec) moved to URL:

Example #2

Window Location Redirect with Time Limit.

Code:

h1 { text-align: center; color: brown; } p { font-size: 28px; border: solid 3px red; color: green; } input { text-align: center; color: navy; } button { font-size: 22px; font-weight: bold; color: white; background: lightblue; } page to other page through accessing the corresponding URL (Unified Resource Locator). Redirecting URL is also used for sending the user from one URL to another URL. Window.location is the function used in website, while I am reading, I have some doubts with specific topics. Instead of providing everything there itself, we can simply summarize the topic and in between doubtable points can be provide with URL Type URL :<input type=”text” name=”url” function getMyRedirectURL() { var url = document.getElementById(“urlID”).value; document.write(“It will redirect within 3 seconds…..please wait…”);//it will redirect after 3 seconds setTimeout(function() { window.location = url; }, 3000); }

Output:

Example #3

Replace Function URL.

Code:

h1 { text-align: center; color: navy; } p { font-size: 28px; border: double 2px teal; color: lime; } input { text-align: center; color: fuchsia; } .button { text-align: center; } button { font-size: 22px; font-weight: bold; color: white; background: red; } page to other page through accessing the corresponding URL (Unified Resource Locator). Redirecting URL is also used for sending the user from one URL to another URL. Window.location is the function used in website, while I am reading, I have some doubts with specific topics. Instead of providing everything there itself, we can simply summarize the topic and in between doubtable points can be provide with URL function getMyReplaceFun() { }

How Does Substring Work In Typescript

Introduction to TypeScript substring

Web development, programming languages, Software testing & others

Syntax:

The TypeScript substring() method mainly focus on the string characters, and it will be used to specify the indexes, and it returns the new substrings characters in the TypeScript. It can be used to pass the two set of arguments one is starting the characters and the second parameter is the length of the string characters.

var variable name="";  console.log("starting position of the character and end position of the character" + variable name.substr(starting position of the character and end position of the character)); ----some typescript codes based on the user requirements-----

The above code is the basic syntax for using the substr() method in TypeScript based applications.

How does substring Work in TypeScript?

The TypeScript string is one of the class for creating and utilising the string characters in the application. We use substring as one of the default method for split the string characters, and it will have concatenated using the length. This method will accept both numeric and non-numeric characters in the script. The string characters are starting with the beginning position of the specific location through the characters for each character; it will calculate the length.

By using the length method, we can calculate the character’s length, and with the help of for loop, we can iterate the values and calculate the character’s length and validate the conditions based on their coder suggestions. Basically, the substring() method is pre-defined, and also it’s an inbuilt function for users to return the subset of the string objects. The argument and the parameters of the substring() method which represents the starting and ending indexes which can be used for to identify the characters and the substring() method which swaps the two set of arguments if the indexStart is greater than the indexEnd position and the string which is still returned position of the variables in the functions.

When we use the string characters index with the help of the indexOf method, the substring method that is not to be used as the really purpose its main job is to return the indexes at the given substring is found on the TypeScript code.

Examples of TypeScript substring

Given below are the examples of TypeScript substring:

Example #1

Code:

var vars = "Welcome to My Domain Have a Nice Day iehf oiefb woeqiurfb iweofbc2iwe bic b newoinu"; var vars1 = "wugdv uidchh e237ed b 374trc hegdc jihefu jehdb jehfb jehb jhebi kbjeij heib jbie h"; var vars2 = "oehqf eub jbqe ijbj jb3e obe bou jbe joj3buier jorub jbj jboui e1r jobeur b ijoe iojef"; var vars3 = "dguy i eebc b eihyeuib f c uiycei ubc3  iurf eurv eub irfub o iobr ibr iu ior iou iub"; var vars4 = "oyed uery euir rui hu48 biury848 buy84 bui fj rhuj hrf hu iho4hi or4ui roh4ih rouiro h"; console.log("(2,3): "    + vars.substr(2,3)); console.log("(-3,4): "   + vars.substr(-3,4)); console.log("(3): "      + vars1.substr(3)); console.log("(-16, 3): " + vars2.substr(-16,3)); console.log("(12, 3): "  + vars2.substr(12,3)); console.log("(15, 5): "  + vars3.substr(15,5)); console.log("(17, 12): "  + vars4.substr(17,12));

Output:

In the above example, we used the substr() method in the different sequences. We used a numeric set of characters that is we can fetch and identified only the integer numbers that will be covered using both positive and negative numbers. With the help of the console.log() method, we can print the values in the output console by using the var keyword; we can declare the variable values by using the string quotations. Generally, the var datatype includes numeric and non-numeric characters here; we can cover the numeric value with the specified index positions for each step, and the variable values declared in the user input end.

Example #2

Code:

var vars = "Welcome to My Domain Have a Nice Day iehf okjwdkg kewgk jdgkiwye iugeigu buir br"; var vars1 = "wuhsgf jdghj 326875 38 3846 86347484 8634r 39846 468 48465 386 34798 94865 946"; var vars2 = "f wqd qw qwuef3287 j6487 jg857 kjg85 jy4587 ng875 gr8 jgweuf 478 jgeru 74"; var vars3 = " hjqwdf jhgds ieyw jhgu jhger 457 jgevr u5 jbi5t78 njerv 5u jngu5 biu5yn bnn uy5 r"; var vars4 = "wf jhqgwf37 jhg u4t jhuy bvu5y4 bv5n bv457b u45t7 bu54tg biu45y buy55y jhgu b ut bu"; var vars5 = new String( "Have a Nice Day" ); var ind = vars.indexOf( "jg jdsvh jsjv bj b kjbd sdbsksd bs dbs db bd" ); console.log("Your first output result is :" + ind ); console.log("Your second output result is:" + ind1 );

Output:

In the second example, we used indexOf() is one of the default child methods in the substring() method; with the help of this method, we can fetch and retrieve the indexing values and the position of the string characters. Additionally, we used var5 variable values; we can create the string object and store it as the separate memory address and its reference.

Example #3 var vars = "Welcome to My Domain Have a Nice Day iehf okjwdkg kewgk jdgkiwye iugeigu buir br"; var output = /My/gi; if (vars.search(output) == -1 ) { console.log("Sorry user it does not contain your values" ); } else { console.log("Thanks user it contains  your values" ); }

Output:

In the final example, we used the search() method for searching the characters, which is declared on the user input variable. We can also search and store the input characters using the other variable with the same data type(var). The search() method is one of the child method in the substring() function of the string classes.

Conclusion

The substring() method is one of the default and frequently used as the string classes in TypeScript. With the help of its child methods like search(), indexOf(), substr() methods, we can achieve this functionality like to calculate the starting and indexing position of the string characters and using loop/conditional statements for evaluating the values.

How Does Classtag Work In Scala?

Definition of Scala Classtag

Web development, programming languages, Software testing & others

Syntax:

As now we know is it the approach to determine and handle the element at the runtime so we have different approaches for that. Let’s have a look at its syntax as per the Scala doc see below;

def method_name[T]: return_type { }

In the above lines of syntax, we have to give the name of the method followed by the return type. This method will return any type of element.

How does ClassTag Work in Scala?

As now we know that classtag is used to handle the element whose types are unknown at the runtime. If we do not handle this properly then we can get many exceptions while programming, for example, classCastException, etc. We have ‘Any’ type in Scala, that can hold any element type inside it. for example, it can be Integer, String. float, and many more. So let’s see one scenario where we have a map that can take up ‘Any’ as the value, but we have to handle it properly otherwise, the code will not work because, at the compile time, we do not know what kind of element it is holding, at runtime only we will get to know.

Let’s have a scenario where we need to handle our array data properly in order to avoid any exceptions while handling the data; see below;

Map[String, Any]: This map is holding key-value pair as String and Any. We can easily handle the key ‘String’ here because the element type is known at compile time only. But if we look at the ‘Any’ value of the map, then we cannot guess what it will hold. It can be anything, so we will see some approaches where we will see how to handle this situation using ClassTag[T] in Scala. See below;

We have three different approaches to this. We will discuss each of them in detail with all the scenarios and exceptions we can get while doing this let’s discuss each of them in detail see below;

To check the instance of the element.

To assign them to any specific type

Use of classtag in scala

1. To Check the Instance of The Element var result = map("12").asInstanceOf[Int];

In the above lines of code, we have our map in which the value comes out to be ’12’, which can be easily cast to int without any error or exception. This will run fine until the value is coming out to be an integer here. But the problem will occur when the value is string here. Let’s take one code snippet see below;

var result = map("Hello").asInstanceOf[Int];

In the above lines of code, we are trying to cast a string then we will get classCastException here. So we are not able to handle this properly, and this line of code is erroneous. We can resolve this by using the classtag in Scala. This can only be determined at runtime only.

2. To Assign Them to Any Specific Type

In this approach, what we are trying to do is we are directly assigning the value to a variable without typecast, but we will going to get the error at compile time only. Let’s see one code snippet where we can understand it better. See below;

var result: Int = map("Hello");

In the above line of code, we are assigning values to solve this problem. We can use an instance of the method here available in Scala, but this is also not the correct approach to solve this because we have already seen we might get some different values while typecasting it, so better to take a better approach to solve this. Here we can use ClassTag[T] available in Scala.

3. Use of ClassTag in Scala def getThevaleFromMap[T]():Option[t]{ } Examples of Scala ClassTag

In this example, we are converting the map values by using ClassTag[T] approach, this is a simple program for beginners to understand it better.

Example

Code:

object Main extends App{ def getConvertedvalues[T](myKey: String, mymap: Map[String, Any]): Option[T] = { println("Here we are calculationg values : ") mymap.get(myKey) match { } } var result1: Option[String] = getConvertedvalues[String]("String1", mymap1) println("Result is after following classtag is  :::") println(result1) println("**********************************************************************") var result2: Option[String] = getConvertedvalues[String]("String2", mymap1) println("Result is after following classtag is  :::") println(result1) println("**********************************************************************") var result3: Option[Int] = getConvertedvalues[Int]("String3", mymap1) println("Result is after following classtag is  :::") println(result1) println("**********************************************************************") var result4: Option[Int] = getConvertedvalues[Int]("String4", mymap1) println("Result is after following classtag is  :::") println(result1) println("**********************************************************************") var result5: Option[Int] = getConvertedvalues[Int]("String5", mymap1) println("Result is after following classtag is  :::") println(result1) println("**********************************************************************") }

Output:

Conclusion

By using classtag we can handle the element of list and map or collection we can say at runtime when we are not aware of the element type at the compile time; this approach or the use of classtag can prevent to occur various errors or exceptions in the program like Incompatible type, classCastException and many more makes our program more scalable and reduce the number of lines of code that being return for other return types.

How Does The Filter_Var Function Work In Php?

Introduction to PHP filter_var

Php filter_var() is a function that is used to filter a given variable with a specified filter. To sanitize and validate the data such as email_id, IP address, etc., in Php, the filter_var() function is used (which contains the data). Validation in the text means whether the entered data is in the correct format or not. For example, in an email id of the person, whether the ‘@’ sign is present or not. In a phone number field, all the numbers or digits should be present. Sanitization means to sanitize the data entered or remove the illegal or unnecessary characters from it to prevent any future issues. For example, removing unnecessary symbols and characters from user email.

Start Your Free Software Development Course

Web development, programming languages, Software testing & others

Syntax:

filter_var(variable, filtername, options)

where,

variable: This parameter stands for the variable field, the variable which needs to be filtered. It is the mandatory field.

filtername: This parameter stands for the name of the filter which the user wants to use. It is an optional parameter. If not specified, FILTER_DEFAULT is used, which means that not filtering would be done to the given variable.

options: This parameter is optional. It specifies the options/ flags to be used. It is basically an associative array of bitwise disjunctions of flags or options. If this parameter is used in the filter_var() function, a flag must be provided in the ‘flags’ field, and a callable type must be passed for the callback function. After accepting all the parameters, the filtered and sanitized variable is returned.

Return Value: The above function returns the filtered value or false if the data/ variable does not get filtered.

How does the filter_var function work in Php?

In PHP, the filter_var() method accepts the above-explained various parameters and returns the validated/ sanitized data. Validation means checking the format of the data as specified by the programmer, and Sanitization means removing the unnecessary characters from the data to return the data as required by the programmer.

Examples of PHP filter_var

Let us understand the working of the filter_var() function in Php along with the examples:

Example #1

Validating an Integer value using filter_var() function:

Code:

<?php $value = 789787; if (filter_var($value, FILTER_VALIDATE_INT)) { echo(“Congratulations!!! $value is a valid integer value”); } else { echo(“Sorry!! $value is not a valid integer value”); }

Output:

Explanation:

In the above code, the Integer value to be validated is stored in the variable ‘value’ and is then passed in the filter_var() method along with the ‘FILTER_VALIDATE_INT’ filter name to validate it. Finally, conditional operators if and else are applied to check the condition, and the respective output is printed on the console using the ‘echo.’

Example #2

Validating the IP address of the computer device using the filter_var() function

Code:

<?php $ip = ‘180.0.0’; if (filter_var($ip, FILTER_VALIDATE_IP)){ echo(“Congratulations!! $ip is a valid IP address, passed by the you”); } else { echo(“Sorry $ip is an incorrect IP address”); }

Output:

In the above code, the IP address of the computer or any other network device is validated using the filter_var() method. The ip address that is to be validated is stored in the variable ‘ip.’ Since the IP address has its specific format ‘x.y.z.w,’ it is validated using the ‘FILTER_VALIDATE_IP’ in the filter_var() function. Finally, the ip address passed is validated, and the respective output is printed on the console using ‘echo.’

Example #3

Sanitizing and Validating the URL address using the filter_var() function

Code: 

<?php $check_url = filter_var($check_url, FILTER_SANITIZE_URL); if(!filter_var($check_url, FILTER_VALIDATE_URL) == false) { echo(“Congratulations!!! $check_url is the correct URL”); } else { echo(“Sorry!! $check_url is an invalid URL”); }

Output:

Explanation:

In the above code, the URL address, which has a specific format, is sanitized first and then validated using the filter_var() method. The URL to be checked is stored in the variable ‘check_url.’ To sanitize the url, ‘FILTER_SANITIZE_URL’ is passed as a filter name along with the url. Once sanitized, url is then validated using the ‘FILTER_VALIDATE_URL’ filter name along with the url, and the respective output on validation is printed on the console using ‘echo.’

Example #4

Validating the email address of the user using the filter_var() function

Code:

<?php $email_check = “[email protected]”; if (filter_var($email_check, FILTER_VALIDATE_EMAIL)) { echo(“Congratulations!! $email_check is a valid email address”); } else { echo(“Sorry!! You have entered an incorrect email address”); }

Explanation:

In the above example, the email address which is to be checked is stored in the variable ‘email_check.’ It is validated using the filter_var() function in Php, bypassing the email variable and the respective filter name (FILTER_VALIDATE_EMAIL). Since the passed email is invalid, so the response is printed on the console using the ‘echo.’

Example #5

Code:

<?php $value = 465675; { echo “Integer $value is within the specified range”; } else { echo “Sorry!! Integer $value is not in the range provided by you”; }

Output:

Explanation:

In the above example, the Integer value is to be validated for the given range, i.e., 10 to 400 is tested. Then, in the filter_var() function, the value to be tested is passed along with the filter name (FILTER_VALIDATE_INT) and 1 optional parameter, i.e., ‘options’ having the array with the minimum and maximum range specified. Finally, the variable is validated, and accordingly, the response is printed on the console using the ‘echo.’

Conclusion

The above description clearly explains what is filter_var() functions in Php and how it works to validate and sanitize the variable passed in it. It is one of the important functions that programmers commonly use to filter the data to prevent a security breach. However, this function facilitates the use of different filters by passing the different parameters according to the specific requirements, so the programmer needs to understand it deeply before using it in the program.
