There is no built-in function to reverse a String in Python. The fastest (and easiest?) way is to use a slice that steps backwards,-1. ExampleGet your own Python Server Reverse the string "Hello World": txt ="Hello World"[::-1] ...
Explanation :In the above code, string is passed as an argument to a recursive function to reverse the string. In the function, the base condition is that if the length of the string is equal to 0, the string is returned. If not equal to 0, the reverse function is recursively called ...

my_string = "Python" reversed_string = my_string[::-1] print(reversed_string) # nohtyP Slicing syntax is [start:stop:step]. In this case, both start and stop are omitted, i.e., we go from start all the way to the end, with a step size of -1. As a result, the new string...
In this article, you will learn5 different ways to reverse the string in Python. 1) Using for Loop Example: # Program to explain reverse string or sentence# Using for loop# Reverse String without using reverse function# Define a functiondefreverse_for(string):# Declare a string variablerstri...
Write a Python program to reverse a string. Sample String:"1234abcd" Expected Output:"dcba4321" Sample Solution-1: 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 reve...
The easiest and fastest way to reverse a string in Python is to use the slice operator [start:stop:step]. When you pass a step of -1 and omit the start and end values, the slice operator reverses the string. A more verbose, but readable (and slower) version of the string reversal ...
