title: Find Python module filename
body: <p>I got module name which contains declaration of <code>os.path.isfile</code>. <a href="https://github.com/davidhalter/jedi" rel="noreferrer">Jedi</a> lib gave me <code>genericpath</code> (without file path). Now i want to get full filename of PY file with this <code>genericpath</code> module. E.g. "C:\Py27\Lib\genericpath.py". How can I do it? Jedi cannot do it?</p>
