simply open the python shell and type help('modules'). You will get a list of all built-in modules.

Python 3.7.4 (tags/v3.7.4:e09359112e, Jul  8 2019, 19:29:22) [MSC v.1916 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license()" for more information.
>>> help('modules')

Please wait a moment while I gather a list of all available modules...
