Achieving Cross-Module Variables without Global Scope

In Python, the __debug__ variable poses as a convenient tool across all modules. Aiming to replicate its virtue, a custom variable named foo can be created to achieve similar functionality. However, unlike __debug__, foo need not be truly global, allowing its value to be set even before importing linked modules.

To realize this, a simple global module-level variable does the trick. Here's an example:

# a.py
var = 1

# b.py
import a
print(a.var)
import c
print(a.var)

# c.py
import a
a.var = 2

When executed as python b.py, the output reads 1 2, demonstrating the universal visibility of var across modules.

This approach proves useful in scenarios such as Django's global_settings.py, where settings are accessed via the imported object django.conf.settings.
