... Wow. Holy wow.
Ok. I don't know the LearnStreet folks, but if that's the quality of
the problem set, that's a big warning sign for me. If that's their
response, then I do stand by what I said earlier. Any "beginning
tutorial" material that is using isinstance() there, as a motivating
reason to use basic loops and conditions, is not to be trusted. That
sounds like the school of "take grab-bag random features of the
language and dole them out in lessons."
I'd recommend a curriculum that respects their audience. Alan Gauld
has written a good tutorial, which you can find here:

Also consider "How to Think like a Computer Scientist".
