Feb 21, 2025 · Explanation: is_palindrome (s, i, j) checks if a string is a palindrome by using two pointers, i (left) and j (right). If i >= j, it returns True as all characters matched. If s [i] != s [j], it returns False due to a mismatch. Otherwise, it recursively checks the inner substring with i + …

Jan 31, 2024 · This article explains how to write Python programs to check whether a string is palindrome or not using methods like for loop, while loop, string slicing, etc with examples.

Oct 6, 2021 · In this tutorial, you’ll learn how to use Python to check if a string is a palindrome. You’ll learn six different ways to check if a string is a palindrome, including using string indexing, for loops, the reversed() function.

# Program to check if a string is palindrome or not my_str = 'aIbohPhoBiA' # make it suitable for caseless comparison my_str = my_str.casefold() # reverse the string rev_str = reversed(my_str) # check if the string is equal to its reverse if list(my_str) == list(rev_str): print("The string is a palindrome.") else: print("The string is not a ...

Nov 15, 2016 · To check sentence palindrome-ness, the algorithm seems to be: Compare new_s to new_s[::-1] case-insensitively. You can do the former by doing: Then the latter by doing: Put the whole thing together with: valid = set(string.ascii_letters) result_s = ''.join([ch for ch in s if ch in valid]) cf_s = result_s.casefold() return cf_s == cf_s[::-1]

Dec 5, 2024 · To check a Palindrome in Python, the program should check whether a given string is the same when read forwards and backward. Consider the following Python program. First, it asks the user to enter a string and stores it. Then, it checks if the string is same as its reverse.

Writing a program to check whether a given input is a palindrome or not can be a fun and interesting coding exercise. We will provide you with a step-by-step guide, along with example code, to help you understand the concept better.

I have a code to check whether a word is palindrome or not: if str[index] == str[p]: index = index + 1. p = p-1. print("String is a palindrome") break. else: print("string is not a palindrome")

This tutorial will teach you how to check if a string is a palindrome in Python. We will walk through the steps of implementing a palindrome checker using different approaches and provide examples for each.

Oct 5, 2019 · Given a string, write a python function to check if it is palindrome or not. A string is said to be palindrome if reverse of the string is same as string. For example, “radar” is palindrome, but “radix” is not palindrome.
