Would anyone be able to explain why "hello" is being printed when the program is run? I was expecting only the welcome_frame to be run as that is the frame that has been raised, but that doesn't seem to be the case.
So why are all classes instantly run when I start the program, and how can I stop this from happening?
What I want is a button to be pressed within the welcome_frame which causes everything within the edit_booking_frame to be run.
Thank you :)
