Reversing a String Using a For Loop You can also reverse a string in Python by using a for loop to iterate over the characters in the string and append them to a new string in reverse order. Here’s an example:
Reverse string using [::-1] print('Python'[::-1]) # nohtyP Python Slice Operator Syntax Slice() returns a slice of the object for a specified sequence (string, tuple, list, range, or bytes). Slicing allows you to write clear, concise and readable code. Python slice() Syntax slice...
Original String is: PythonForBeginners Reversed String is: srennigeBroFnohtyP Reverse string using for loop To reverse a string using a for loop, we will first calculate the length of the string. Then, we will create a new empty string. Afterwards, We will access the string character by ...
Python string library does’nt support the in-built “reverse()” as done by other python containers like list, hence knowing other methods to reverse string can prove to be useful. This article discusses several ways to achieve it. Using loop # Python code to reverse a string # using loop...
The input string "Java Program" is defined, and we convert it into a character array. Using a for loop, each character is pushed onto the stack. As the stack follows LIFO, popping elements from it will yield the characters in reverse order, which are stored in a new character array. ...
Python Code: # Define a function named 'string_reverse' that takes a string 'str1' as inputdefstring_reverse(str1):# Initialize an empty string 'rstr1' to store the reversed stringrstr1=''# Calculate the length of the input string 'str1'index=len(str1)# Execute a while loop until...

Reverse a string using for loop Next, we'll be using a simple for loop to reverse a string. const str = "hello world!"; let strReverse = ""; for (let i = str.length - 1; i >= 0; i--) { strReverse = strReverse + str[i]; } console.log(strReverse); // Output: !dlrow...
Since we can't use the library function, In the function - we run a for loop to reverse the strings by storing the sequence in reverse order in the variable $rev. An additional while loop is set up to check if the variable $text contains a valid string (i.e. to calculate the ...
Method 2: Using a Loop Another straightforward approach to reverse a string in C++ is by using a loop. This method gives you more control over the process and can be a great learning experience. Here’s how you can implement string reversal using a loop: ...
