They are not totally bad and most real programs wind up
having one or two globals, although usually those globals
are top level container classes, perhaps even an Application
class or similar.

This would be a cyclical import and is bad even if it does not fail.
Remove the common dependencies (in this case the global variables)
and place it in a

I know they are bad. That is why I would prefer not to use it, but I am not
sure how else to handle this problem.
In this app, the user must log in. Once authenticated, they have a userid
stored in the SQLite database. Before splitting my app into multiple files, I
used a global variable.

I'm a bit confused about extracting data using re.search or re.findall.
Say I have the following code: tuples =
re.findall(r'blahblah(\d+)yattayattayatta(\w+)moreblahblahblah(\w+)over',
text)
So I'm looking for that string in 'text', and I intend to extract the parts
which have parentheses around

Okay - I am officially embarrassed.
As you might now, I am splitting this 10,000 line file apart, and that is
posing certain challenges which I am fixing, and cleaning up stuff that was
broken and visible only when doing this split.
This is one of them.

The call to bool is redundant. Get rid of it. The not operator will
automatically convert its argument into a
