How do I retrieve a modules path when I have a class from that module
<p>In python, If I have a class <code>foo</code>, I can <code>call foo.__module__</code> to get a string with the name of the module it is part of.</p>

<p>If I have a module <code>bar</code>, I can call <code>bar.__file__</code> to get a string with the path where the module was loaded from.</p>

<p>How, when I only have class foo can I get the path of the module it is part of? (<code>foo.__module__</code> returns a string, not an instance of the module it names)</p>
