String operations in python is the computation applied to the variable in an expression. It can be done using various operators like (+),(*).

In Python, the sequence of characters enclosed within the quotes is called a string. It can be enclosed in single, double, or triple quotes. For example, “python”, ” blog”, etc.

It is the computation or actions applied to the variable containing string data types in an expression. String manipulation in Python can be done using various operators like concatenation (+), repetition (*), slicing of string, and membership operators( in /not in). So, Let’s understand each operator in brief

12/100: I studied a good bit and my interview went well, I think! I realized that there was a better way to solve the problem after the interview. So, I went and implemented that and emailed the better solution to my interviewer. I felt good about studying and really knowing my stuff.

Do you know how to reverse a string in python? The reverse of a string is means simply writing the string from last in a reverse manner...

Reverse of a string is means simply writing the string from last to the first index in a reverse manner. Likewise, the reverse of “python” will be “nohtyp”.

But, Python does not have any built-in function to reverse a string. However, it can be done in several ways.

A Palindrome program in python is a program to check whether a string spells the same from both forward and backward direction, for eg; madam

A palindrome is a word, number, or any sequence of characters that spell the same whether read in forward or backward direction.

The Python program to check whether the given string is palindrome or not can be created using different methods.

String methods in python are the built-in function of python used for string manipulation. For example, len() is the basic inbuilt string method. Syntax: .() There 45+ string method in python: 1. capitalize() 2. casefold 3. count 4. isalnum 5. isdecimal ...

String methods are the built-in function of python used for string manipulation.len() is the basic inbuilt string method. They are also called string functions. However, Python follows the following syntax for using other string functions:<string object>.<method name>( )

How To Reverse A String With Built-In Functions

In JavaScript there is no single built-in function to reverse a string so we will use three functions:

1. split(): this will split a String object into a string array 2. reverse(): this will reverse an array 3. join(): this will join all elements of an array into a string.

Here is a complete example:

1 2 3

function reverseString(str) { return str.split("").reverse().join(""); }

How To Replace All String Occurrences In JavaScript ?

JavaScript's replace function only removes the first occurrence of the string. To replace of occurrences of a string in another string we can use Regular expressions.

Here is an example of a function that replaces all string occurrences in another string:

1 2 3

function replaceAll(originalString, stringToFind, stringToReplace) { return originalString.replace(new RegExp(escapeRegExp(stringToFind), 'g'), stringToReplace); }

How to process each letter of a string

Here is a simple solution to loop trough a string an process each character. Code:

1 2 3 4 5 6

var str="My string to process." for (var x = 0; x < str.length; x++) { var c = str.charAt(x); alert(c); }
