Just realized that you've asked for installed packages. Perhaps the following will do the trick. I don't know why the 'lib-tk' isn't included. Why not?
toplevel_packages = ['%s\\%s'%(ml.path,name)for ml,name,ispkg in pkgutil.iter_modules() if ispkg] print '\n'.join(toplevel_packages) > Date: Sat, 8 Jun 2013 21:30:48 -0700 > Subject: Listing modules from all installed packages > From: jpha...@gmail.com > To: python-list@python.org > > 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).
