Question 3 - Long Answer Type Questions (5 Marks each) - Chapter 8 Class 11 - Strings

Write a program that reads a string and check whether it is a palindrome string or not.

Answer:

Code:

str=input( "Enter a string: " )

rev=str[:: -1 ]

if str==rev:

    print("Given string is a palindrome")

else:

    print("Given string is not a palindrome")  

Explanation:

A string is a palindrome if it reads the same forwards and backwards.

A string can be reversed in python using the slice operation . If we ignore both the indexes and give step size as -1, the string is printed in reverse.

Now the entered string and the reversed string are compared to check whether the string is a palindrome or not.
