Namespace problem

[Geiger Ho]

Hi all,

Consider:

File1.py:
---------
import File2
import File3

class A:
  def __init__(self):
      self.b = File2.B()
      self.c = File3.C()
  def run():
      pass

if __name__ == '__main__':
  a = A()
  a.run()


File2.py:
---------
class B:
  def foo(self):
      pass

File3.py:
---------
class C:
  def fun(self):
      # a method need to callback a.b.foo()
      # how can I implement

Question:
How should I call the a.b.foo() in the fun method?

Thanks in advance.

Regards,
Geiger
