As a professional Python programmer, I regularly search for the official documentation on things like the details of MagicMock or other things, for both Django and Python. I'm generally looking up things that are more than "what does str.endswith do", and more like "what's the name of the field of the mock that shows what it was called with", or other things that I know exist but don't use day-to-day.
