Thank you for the help..I think I'm getting closer, but I feel like after they
enter an invalid number, it should reset the invalid number(s) somehow. Here's

I'm sorry it's so frustrating. Sounds like you haven't got down some of

Howdy all,
Ever since Python's much-celebrated Grand Unification of classes and
types, I have used those terms interchangeably: every class is a type,
and every type is a class.
That may be an unwise conflation. With the recent rise of optional type
annotation in Python 3, more people are speakin

As an approach, that looks ok. The code looks a bit too lenient, though,

That doesn't represent the whole truth. The Usenet group is
