Write a function called is$\_$palindrome. A Palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. This function should take in one parameter and returns True or False depending on whether it is a palindrome. Print

As a bonus, allow your function to ignore whitespace and capitalization so that is$\_$palindrome$(\text{'}$a man a plan a canal Panama'$)$ returns True.
