We have tried several different things and can't come up with a successful command.  Any help you can give will be much appreciated!!
There are two ways to get those totals, depending on whether you know
how to work lists or not.  If you do, then you should make a list of
occupied_rooms, and sum() it at the end, and make a list of
rooms_on_flow, and sum that at the end.

But as you discovered, sum() won't work on an int (BTW, you should give
the entire traceback instead of saying "doesn't work".  In this case, it
was obvious, but it might not be.)

On the other hand, if you don't know what a list is, then you need to
accumulate those numbers as you go.  Either way, you need extra
variables to represent the whole hotel, and you need to do something
inside the loop to adjust those variables.
