Probably you want to iterate over sys.modules -- one way to do this is:

    for k in sys.modules.keys():
        module = sys.modules[k]
        print module.__version__

However you will need to ensure that a particular module HAS a __version__
attribute before referencing it, or trap the AttributeError exception which
will result when it doesn't.
