+### palindrome
+
+Returns `True` if the given string is a palindrome, `False` otherwise.
+
+Convert string `str.lower()` and use `re.sub` to remove non-alphanumeric characters from it. Then compare the new string to the reversed.
+
+```python
+def palindrome(string):
+    from re import sub
+    s = sub('[\W_]', '', string.lower())
+    return s == s[::-1]
+```
+```python
+palindrome('taco cat') # True
+```
