Why not?

---------
File a.py:

  class MyClass:
      def foo(self, x):
          return x * 6

---------
File b.py:

  import a
  def bar(self):
      print 'bar'
  def baz(self, a):
      print self.foooo(a)

  # adding methods by hand:
  a.MyClass.bar = bar
  a.MyClass.baz = baz

---------
File c.py

  import a
  def foooo(self, a):
      return a * self.foo(4)
  def baaar(self):
      print self.baz('tralala')
  def bazzz(self):
      print 'bzzzzzzzzzz'

  # adding methods more automaticly:
  for name, obj in globals().values():
      setattr(a.MyClass, name, obj)

It's a good question. As others said it's very probable that some other
solution would be better (e.g. inheritance).
