Lecture 75:-  Check For Palindrome In Python

A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward. To check if a given string is a palindrome in Python, you can compare the original string with its reverse. If they are the same, then the string is a palindrome.

Here's a simple function to check for a palindrome in Python:

pythonCopy code

def is_palindrome(string):    # Remove non-alphanumeric characters and convert to lowercase    cleaned_string = ''.join(char.lower() for char in string if char.isalnum())    return cleaned_string == cleaned_string[::-1] # Example usage: text1 = "radar" text2 = "hello" print(is_palindrome(text1))  # Output: True print(is_palindrome(text2))  # Output: False

In this example, the is_palindrome() function takes a string as input and removes all non-alphanumeric characters (such as spaces, punctuation, etc.) using a list comprehension and the isalnum() method. It then converts the cleaned string to lowercase.

Finally, it compares the cleaned string with its reverse (cleaned_string[::-1]) using the == operator. If the original string and its reverse are the same, the function returns True, indicating that the string is a palindrome; otherwise, it returns False.

Keep in mind that this implementation is case-insensitive and ignores spaces and punctuation. If you want a case-sensitive palindrome check or need to handle specific characters differently, you can modify the function accordingly.
