Lecture 4 code: I'm having a hard time understanding the second line in the isPalindrome(s) function. Shouldn't the function hit the first return and then exit without computing the isPalindrome(s[1:-1])?

    Here's the code: def isPalindrome(s): """Returns True if s is a palindrome and False otherwise""" if len(s) <= 1: return True else: return s[0] == s[-1] and isPalindrome(s[1:-1])

    Actually nevermind, The two expressions are boolean and the "and" in between them acts like a logical operator.
