I know they are bad. That is why I would prefer not to use it, but I am not

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.

list1 = [1,2,3]
list2 = ['a', 'b', 'c']
item = random.choice(list1 +list2)
if item in list1:
