How do you do this exactly?

They are in a "setOptions" function in config.py, which reads from an
ini file and sets up all options for the program. All other files then
can read these options. For example, anyone else can import config,
then, if they are rounding a number, they can know how many places to
round to by looking at config.rnd. I have everything in a function
instead of being initialized upon importing since I offer a function
to reload the ini file if the user changes something. Eventually I
will have a gui for setting options, and that gui, to save options,
will write an ini file then call setOptions so all options are then
reset according to the newly created ini. If I do not make everything
in setOptions global, no other file seems able to read it; I get an
exception the first time another file tries to access a setting.
Thanks.
