I were to convert the view to a tkinter GUI, where would the root.mainloop() statement go? In the controller's main() method? What GUI-related stumbling blocks might I easily run into in going from CLI to GUI with this existing code? 3) If I were to add data files in place of (or in

Re: [Tutor] Correct use of model-view-controller design pattern

[Tutor] Py 2.4.4: Inheriting from ftplib.FTP()

I have actually successfully connected to the FTP server. Is there a better way to check for connection success? 4) As this class stuff is mostly treading new ground for me, am I doing anything that I should not be doing or should do in a more preferred way? Keep in mind that I am just starting on this code today.
