In the documentation for the inspect module, the module type is described with just 2 of its potential 7 attributes.  The language reference[2] and importlib docs[3] both provide an accurate list of module attributes.

Furthermore, the description for __file__ should be fixed.  It should be clear that __file__ reflects the location from which the module was loaded, that location is not necessarily a filename, and the attribute may not exist if the module was not loaded from a specific location (e.g. builtin and frozen modules).  The same goes for __cached__
