Comparing Strings for palindrome

Question

If I reverse a string using [::-1] can I then just compare it to the original to test if it is a palindrome? My other plan is to create a list or set with the alphabet in it and index the letters of the string to compare numerically if the simple way doesn't work out.

... did you try it out??? Why do you think it won't work? – juanpa.arrivillaga Nov 01 '17 at 21:40 — juanpa.arrivillaga, Nov 01 '17 at 21:40

Yes. You can.

def is_palindrome(a_string):
    if a_string == a_string[::-1]:
        return True
    return False

Or simpler:

def is_a_palindrome(a_string):
    return a_string == a_string[::-1]

`if True: return True`? – Joran Beasley Nov 01 '17 at 21:44
