If I understand your question right, you want some way to automatically  
enumerate and import all *.py files inside your package. Try this inside  
Foo/__init__.py:


def import_all_modules():
 "Import all modules in this directory"
 import os.path
 pkgdir = os.path.dirname(__file__)
 for filename in os.listdir(pkgdir):
 modname, ext = os.path.splitext(filename)
 if ext=='.py' and modname!='__init__':
 __import__(modname, globals())

import_all_modules()
del import_all_modules

from x import y as z



that has always worked for me to prevent pollution...

Library package import question

2007-11-05 Thread Frank Aune 
Hello,

I have a python library package 'Foo', which contains alot of submodules:

Foo/:
__init__.py
module1.py:
class Bar()
class Hmm()
module2.py
class Bee()
class Wax()
module3.py
etc etc

To prevent namespace pollution, I want to import and use this library in the 
following way:

import Foo
(...)
t = Foo.module2.Bee()

To accomplish this, I put explicit imports in __init__.py:

import module1
import module2
import module3

what Im wondering about, is if its a more refined way of doing this, as the 
explicit imports now need to be manually maintained if the library grows. 
I've tried to use __all__, but this only seems to work with "from Foo import 
*" and it causes modules to be imported directly into the namespace of 
course.

Thanks for input.
-Frank
