Palindrome

🎯 Write a function that checks whether a string is a palindrome:

def is_palindrome(s):
    ...

Tests

Test your function with this code:

assert is_palindrome('Abba')
assert is_palindrome('kayak')
assert is_palindrome('Rats live on no evil star')
assert not is_palindrome('abc')
assert not is_palindrome('Hello world')

Hints

• remove whitespace

• ignore punctuation marks

• ignore upper/lower case

• you find more palindromes on Wikipedia.
