Also worth mentioning if you're just starting with Python.  Python has 
some official naming conventions:

http://www.python.org/peps/pep-0008.html

These are just recommendations of course, but if you have the option 
(e.g. you're not constrained by style enforced by your employer), and 
you'd like your code to look more like standard Python modules, you 
might consider using these suggestions.  This would make your code look 
something like:

#=============
import file2
global my_base_class
my_base_class = file2.BaseClass()
my_base_class.add_child(file2.NextClass())
#=============

#=============
global my_base_class
class BaseClass:
     def __init__(self):
         self.my_childs = []
      ...
     def add_child(new_child):
         self.my_childs.append(new_child)
     ...
class NextClass:
     def __init__(self):
         for each_child in my_base_class.my_childs:  # <- ERROR
             ...
#=============
