Write a Python function isPalindrome() that checks whether a passed string is palindrome or not. If the parameter string is a palindrome, then the function will return True, otherwise it will return False. A palindrome is a word, phrase, or sequence that reads the same backward as forward, e.g., "madam" or "nurses run" or "Madam I'm Adam!" or "Was it a cat I saw?". The function can check if given string is a palindrome or not, by following the steps given below: 1. Create a new string that only contains the alphanumeric characters, i.e. skip the other characters. E.g.: From string "Madam I'm Adam!", create a new string "MadamImAdam". 2. Convert this new string to upper case. Eg: from "MadamImAdam", get "MADAMIMADAM". 3. Compare with its reverse. If the new string is equal to its reverse, then return True, otherwise return False. Write Python statement that reads a string, call the function and print an appropriate message. Part 2: Please enter a string: A man, a plan, a canal, Panama! The string 'A man, a plan, a canal, Panama!' is a palindrome. Part 2: Please enter a string: Good work The string 'Good work' is not a palindrome
