Question

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])?

Answer 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])

Answer 2

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