How to Check a Palindrome in Python

A palindrome is a word, number, or sentence that reads the same forward and backward.

For example:

• madam → madam
• level → level
• 121 → 121
• racecar → racecar

In this blog, we will learn how to check whether a word is a palindrome using Python.

Python Program

word = input("Enter a word: ")

reverse = word[::-1]

if word == reverse:
    print("It is a palindrome")
else:
    print("It is not a palindrome")

How Does the Program Work?

1. Get input from the user

word = input("Enter a word: ")

This asks the user to enter a word.

For example:

Enter a word: madam

2. Reverse the word

reverse = word[::-1]

[::-1] is used to reverse a string.

For example:

madam → madam
hello → olleh

3. Compare the original and reversed words

if word == reverse:

The program checks whether the original word and reversed word are the same.

If they are the same, it is a palindrome.

4. Print the result

print("It is a palindrome")

If the word is a palindrome, the program prints:

It is a palindrome

Otherwise:

It is not a palindrome

Example

Input

Enter a word: level

Output

It is a palindrome

Another example:

Input

Enter a word: python

Output

It is not a palindrome

Conclusion

Checking a palindrome is a simple and useful Python exercise. It helps beginners understand:

• Strings
• User input
• String slicing
• if-else conditions
• Comparing values
