I have written a GUI program where I have quit a few global variables. I did not like this, so I now use one global dict. Something like:
[snip]
global_dict = { 'messages': messages, 'progress': progress, 'window': window, }And in the program do things like: global_dict['progress']['value'] += 1 global_dict['window'].update_idletasks() global_dict['window'].update_idletasks() and: messagebox.showwarning(global_dict['titles']['warning'], global_dict['messages']['nofiles']) Is that an acceptable way to do this?
It works. I guess it makes your use of items in the global namespace inherently intentional rather than allowing accidental globals. I'm not sure how much value it adds though.
That said, I've got a whole bunch of programs that all use a dict called Registry that they all import from a shared package; making them program-wide globals. I use it for a few pieces of static information ('application', 'version') as well as to pass device handles around, since an open connection to a given piece of physical hardware is an inherently global thing.
