Quick answer:
yes it is possible.

Long answer:

C:\Temp>cat > Globals.py
class GV:
  val = 0
    def __iadd__(self, arg):
        self.val += arg
        return self
    def __repr__(self):
        return repr(self.val)

gv = GV()

C:\Temp>cat > A.py
from Globals import gv

class A:
    def __init__(self):
        global gv
        print gv
        gv += 1

C:\Temp>cat > B.py
from Globals import gv

class B:
    def __init__(self):
        global gv
        print gv
        gv += 1

C:\Temp>cat > main.py
import A
import B
a = A.A()
b = B.B()

C:\Temp>main.py
1
