Python Program to Check if a String is Palindrome or Not

Python Program to Check if a String is a Palindrome

In this video, we will explore how to write a Python program to check if a string is a palindrome. A palindrome is a string that reads the same forward and backward, ignoring spaces, punctuation, and capitalization. This tutorial is perfect for students, professionals, or anyone interested in enhancing their Python programming skills.

Why Learn About Palindromes?

Understanding how to check for palindromes helps to:

• Improve your string manipulation skills.
• Solve common algorithmic problems.
• Enhance your problem-solving abilities in programming.

Key Concepts

1. Palindrome:

• A string that reads the same backward as forward. Examples include "madam", "racecar", and "level".

2. String Manipulation:

• Techniques used to process and modify strings in programming.

3. input() Function:

• A built-in Python function used to capture user input.

Steps to Check if a String is a Palindrome

1. Normalize the String:

• Convert the string to lowercase to ensure the comparison is case-insensitive.
• Remove any non-alphanumeric characters to ignore spaces and punctuation.

2. Reverse the String:

• Reverse the normalized string.

3. Compare the Strings:

• Check if the normalized string is equal to its reversed version.

Practical Examples

Example 1: Basic Palindrome Check

Capture Input:

• Prompt the user to enter a string.

Normalize the String:

• Convert the string to lowercase and remove non-alphanumeric characters.

Reverse the String:

• Reverse the normalized string.

Compare and Print Result:

• Compare the normalized string with its reversed version and print whether it is a palindrome.

Practical Applications

Data Validation:

• Use palindrome checks in data validation and text processing applications.

Algorithmic Challenges:

• Solve common algorithmic problems and coding challenges involving palindromes.

Learning Tool:

• Enhance your understanding of string manipulation and algorithm design.
