Question

I have two modules, a.py and b.py. I want the globals from a.py to be available in b.py like this:

a.py:

#!/usr/bin/env python
var = "this is global"
import b
b.foo()

b.py:

#!/usr/bin/env python
var = "this is global"
def foo():
    print var

Currently, I re-declare the globals in each module. There must be an easier way.

Create a settings module that has shared globals if that’s what you want. That way you’re only importing and referencing each global one time, and you’re keeping them isolated within the namespace of the settings module. It’s a good thing.

#settings.py
var = 'this is global'

# a.py
import settings
import b
b.foo()

# b.py
import settings
def foo():
    print settings.var
