Checks if the given string is a palindrome.

• Use str.lower() and re.sub() to convert to lowercase and remove non-alphanumeric characters from the given string.
• Then, compare the new string with its reverse, using slice notation.

from re import sub

def palindrome(s):
  s = sub('[\W_]', '', s.lower())
  return s == s[::-1]

palindrome('taco cat') # True
