Listing installed modules in Python

Here is a basic code I came up with to list modules installed.

import sys as s
mod=s.modules.keys()
for indx,each in enumerate(mod):
    print indx,each

But what I am looking for is, it should only print out the parent module name like for 

 numpy.f2py.pprint'
 numpy.distutils.atexit'
 numpy.distutils.sys'
 numpy.f2py.sys'

It should count it once as Numpy and move to look for next module and repeat same way...

def __listAllModules(self):
    """ This method returns all the modules installed in python
        including the built in ones.
    """
    allmodules = list(sys.builtin_module_names)
    allmodules += list(t[1] for t in pkgutil.iter_modules())
    allmodules = sorted(allmodules)
    return allmodules

import sys
print set([each.split('.')[0] for each in sys.modules.keys()])

import sys as s
mod=s.modules.keys()
mods_seen = list()
for indx,each in enumerate(mod):
    parts = each.split('.')
    if not parts[0] in mods_seen:
        print indx,each
        mods_seen.append(parts[0])

The system command pip freeze does just about what you want, however I'm not entirely certain if it lists all modules or only those installed with pip.
