01 what the model was asked

Create palindrome.py with exactly one function:

is_palindrome(text: str) -> bool
    Return True if text reads the same forwards and backwards, ignoring letter case and ignoring every character that is not a letter or digit. Text with no letters or digits at all (including the empty string) counts as a palindrome.

Use only the Python standard library.
