I am not sure if Python has user defined constants, but a possible 
solution to the scoping problem could be creating a module called 
consts.py. Inside consts.py initialize varibles in with their "constant" 
value. Import that module into your other modules and use 
consts.<variable_name> to reference the pre-initialized variable.

The drawback, of course, is anyone can change the value.

Hope this helps.
