A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward. Here's how you can determine if a string is a palindrome in Python: Method 1: Using Python built-in functions Use the re module to remove all non-alphanumeric characters from the string, and convert it to lowercase. Use the [::-1] slicing notation to reverse the string. Compare the original and reversed strings. If they are the same, the string is a palindrome. pythonCopy code import re def is_palindrome(s): s = re.sub('[^0-9a-zA-Z]+', '', s).lower() return s == s[::-1] Method 2: Using a loop Use a loop to iterate over the first half of the string. Compare the current character with the character at the opposite end of the string. If any characters don't match, the string is not a palindrome. Otherwise, it is. pythonCopy code def is_palindrome(s): for i in range(len(s) // 2): if s[i] != s[len(s) - i - 1]: return False return True Here's an example of using these functions: pythonCopy code >>> is_palindrome("racecar") True >>> is_palindrome("hello") False >>> is_palindrome("A man a plan a canal Panama") True Requirements:
