The global name scope of Python is the module scope.
So it's impossible to refer to entities in other modules
without importing those modules. e.g.

$ cat a.py
# module a

g_var = None

class CA:
    def foo( self ):
        print g_var

$ cat b.py
# module b
import shelve, a
s = shelve.open( 's' )
s[ "va" ] = a.CA()
s.close()

$ cat c.py
# module c
import shelve, a

s = shelve.open( 's', 'r' )
va = s[ "va" ]
s.close()

a.g_var = "the string to be printed"
va.foo()

$ python b.py
$ python c.py
the string to be printed
