Note that there's 13,563 definitions included, so any application that attempts to parse XML structure will have a bad time.
Using the Notepad++ "python.xml" generator at: https://sourceforge.net/projects/npp-python/, in conjunction with a script that imports all Python modules: http://stackoverflow.com/questions/1206832/importing-the-entire-python-standard-library, on a computer with a fresh Python install, nabs a "python.xml" file with definitions and autocomplete entries for all Python Standard Library modules.

Or if github gists are your thing: https://gist.github.com/extramaster/9d0b7eba99a9708eb3f71ae95bcd42b5
The "python.xml" file should be placed in "C:\Program Files (x86)\Notepad++\plugins\APIs" or "C:\Program Files\Notepad++\plugins\APIs", overwriting the pre-installed copy.
In case you want to revert back to the pre-installed "python.xml" file, here's a copy: http://static.extramaster.net/python_original.xml.zip
Here's a list of all of the Python Standard Libraries used in the creation of the autocomplete file:
