    Can I just say, This is a perfect example of why everyone in industry thinks Software Devs have autism...

    The description provided for this task is absolutely appaling...

    Huges pieces of key information missing, assumptions made all over the bloody place. no "Hey, extend this class and implement these new methods, here's how the feed method will class these new classes, etc"...

    Nope, ignore all that shit... lmfao

    In the challenge explantion there is a wrong code; in the example they mentioned the import statement as: from HTMLParser import HTMLParser

    But it should be: from html.parser import HTMLParser

    Please HackerRank team update it.

      Thank you for pointing this out. I've updated the statement.
