Thanks a lot Carlos, this gives me exactly what I needed!

Just realized that you've asked for installed packages. Perhaps the following

toplevel_packages = ['%s\\%s'%(ml.path,name)for ml,name,ispkg in

print '\n'.join(toplevel_packages)

 Hi,
 
 I'm trying to write a function that programmatically obtains and returns the 
 exact location of all first-level modules for all installed packages.
 
 For example, if the packages named 'django' and 'django-debug-toolbar' are 
 installed, I'd like this function to return something like:
  installed_modules()
 /Users/my_user/.virtualenvs/my_venv/lib/python2.6/site-packages/django
 /Users/my_user/.virtualenvs/my_venv/src/debug_toolbar
 
 That is, this function needs to consider all installed packages, including 
 those that have been installed in edit mode (i.e. in the src/ folder). Note 
 also that the main module for the 'django-debug-toolbar' is in fact named 
 'debug_toolbar'.
 
 So far the closest I've been to retrieving the list of first-level modules is 
 as follows:
 
 import os
 import pkg_resources
 import setuptools
 
 pkgs = set()
 
 for dist in pkg_resources.working_set:
 if os.path.isdir(dist.location):
 for pkg in setuptools.find_packages(dist.location):
 if '.' not in pkg:
 pkgs.add(pkg)
 
 The idea is then to loop through that list of modules, import them and get 
 their exact locations by fetching their __file__ attribute values.
 
 However, this feels very hackish and I don't think it's actually quite 
 correct either. I'm sure there must be a better way. If possible I'd also 
 like to avoid having to use setuptools.
 
 Do you have any tips on how to achieve this?
 
 Many thanks!

Adding : python -c 'help(modules) to the other two suggestions:

#!/usr/bin/env python

import commands, pkgutil, re, sys

print('sys.modules.items()...')
print('\n'.join(sorted([re.findall(from '(.*)',str(v))[0] for k,v in 
sys.modules.items() if str(v).find('from')-1])))

print('\npkgutil.iter_modules()...')
toplevel_packages = ['%s\\%s'%(ml.path,name)for ml,name,ispkg in 
sorted(pkgutil.iter_modules()) if ispkg]
print '\n'.join(toplevel_packages)

theCommand = python -c 'help(\modules\)'
print('\n{} # this may take a few seconds...'.format(theCommand))
print(commands.getstatusoutput(theCommand)[1]) # help() only works in the 
python interpreter...

Please use a dictionary to store a tree first.
Then it is trivial to walk through all nodes of the tree.
