Is there a way to creat a func that returns a cursor that can be used?

Yes, and you're almost there!

All you need to do is make use of the return value. Try this instead:

cur = connect()

That takes the returned cursor object and binds it to the name 'cur'
in global scope. You can then use 'cur.execute...' and it'll be the
same object.

As a side point, thank you for posting so clearly. It's easy to help
when your code and traceback are all there!
