Create Palindrome

Have the function Palindrome(str) take the str parameter being passed and return the string true if the parameter is a palindrome, (the string is the same forward as it is backward) otherwise return the string false. For example: "racecar" is also "racecar" backwards. Punctuation and numbers will not be part of the string.
