Palindrome Test

[rootVIII]

Here's a recursive solution that almost gave me an aneurysm:

#! /usr/bin/python3
from sys import argv, exit


def is_palindrome(s):
    if s != '':
        if s[0] != s[-1]:
            return False
        return is_palindrome(s[1:-1])
    return True


if __name__ == "__main__":
    if len(argv) < 2:
        print("Enter a word as an argument")
        exit()
    print(is_palindrome(argv[1]))
