Using freeze command you can check all installed commands.

pip freeze

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.

Does anyone have any tips on how to achieve this?

I have python-django installed on ubuntu installed on top of virtual Box. Also I have apache2 installed in the same way. When i visit the page hoisted by Apache2 from my Windows Host machine it worked.
But When i am doing the same for Django pages it's not opening up in Web browser from Host machine.
In the virtual box I am using bridged adapter and Eth0.

Please Help me to sort out this problem

We have a server running a web-based terminal emulator (based on shellinabox for screen-casting check www.webminal.org) that allows users to learn simple bash commands. This Linux environment secured by things like quota, selinux,ulimit etc

Now some users are requesting python access. How to ensure python is executed in a restricted environment. I came across
http://docs.python.org/2/library/restricted.html
but it seems like disabled in 2.3. Any thoughts on how we can safely provide python access to users.

This isnt a huge issue, but I am wondering. I am running Mac OS X, I tried to configure with --with-valgrind and this is the error that I got:

configure: error: Valgrind support requested but headers not available

Now, I have valgrind installed, so it should work, yes?If someone has any extra info on this, Id appreciate it.
