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.
```py
from re import sub
def palindrome(s):
s = sub('[\W_]', '', s.lower())
return s == s[::-1]
```
```py
palindrome('taco cat') # True
```
