accessing class variables of private classes

Hi,

I need to access class variables of a class I'd like to make private:

i.e.
class __Bar(object):
  pass

class __Foo(__Bar):
  def __init__(self):
    super(__Foo, self).__init__()

>>> __Foo()
Name Error: global name '_Foo__Foo' is not defined

Here I want to prevent the user of instanciating __Foo from outside of the
module.


i.e.
class __A:
  a_list = []
  def __init__(self):
    __A.a_list.append(self)

>>> __A()
NameError: global name '_A__A' is not defined

Here I want to keep a list of instanciated objects of class __A, so I can
update internal values if they are changed.


Any ideas?

Thanks
Uwe
