You could explicitly import __main__ and use that as a global namespace
(see example below). Or (perhaps a better idea), you could have a module
dedicated to global storage, and import that in all your other modules
instead of importing __main__.
---------------------------------
Roy-Smiths-Computer:play$ cat global.py
#!/usr/bin/env python
import a
import b
a.set()
print "x = %s" % x
print "b.get() = %s" % b.get()
---------------------------------
Roy-Smiths-Computer:play$ cat a.py
import __main__
def set():
__main__.x = "hello"
---------------------------------
Roy-Smiths-Computer:play$ cat b.py
import __main__
def get():
return __main__.x
---------------------------------
Roy-Smiths-Computer:play$ ./global.py
x = hello
b.get() = hello
