Returns `True` if the given string is a palindrome, `False` otherwise.
Use `input_string.lower()` and `re.sub()` to convert to lowercase and remove non-alphanumeric characters from the given string.
Use `s.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.
```py
from re import sub
def palindrome(input_string):
s = sub('[\W_]', '', input_string.lower())
def palindrome(s):
s = sub('[\W_]', '', s.lower())
return s == s[::-1]
```
