Thanks for the replies everyone.

I guess Python just doesn't have a "declare-variable-as-global-for-whole-module" feature.

(I don't generally have problems with variable overlap because I'm very careful with naming my global variables.)

(I just remembered though-- for some reason,

list-type variables' individual values/items  can be easily accessed throughout the whole module even if:  it was just "global"ed once inside the function it was created.)

But I just wish I could create variables (of ANY TYPE) which are universally acknowledged by the WHOLE module.

Many of my variables' names are re-stating the exact value they hold, so I rarely have any confliction with names:

filename_of_current_level = 'desert.txt''

Font__New_Times_Roman_size_20 = ...

pi_divided_by_180 = math.pi() / 180

etc.

The names are just according to what values they hold which-- are all unique anyways!

And when the number of variables start reaching the hundreds, it just gets really crazy with "global this global that" ALL OVER my code, again and again . . .

I have to keep remembering to global every other variable in any function that uses my main game variables.

Listen carefully (I say that because this has already been explained to you multiple times). You don't need to use the global keyword to access a global variable in a function if you don't assign to that variable within the function. Two of your three examples (Font__New_Times_Roman_size_20 and pi_divided_by_180) are extremely likely to fall into this category every time they appear in a function. I think if you looked through your code carefully, you'd see that you need far fewer global keywords than you actually think you do.
