In this Bite you parse
social_platformsbelow into a dict of
Validator namedtuples. For each social network you should extract a range and re.compile object.
With the data parsed complete
validate_usernamethat validates a username against a social network of choice (Twitter, Facebook, Reddit here).
The regex might make this a bit more advanced, but as it's an advanced Bite we hope you can draw from the docstrings and tests. Enjoy and keep learning more Python!
