A few things come to mind... Installing it. Setting up a project. Learning the whole language. Reading other people's code. Understanding how things work behind the scenes. Less surprising code, in the sense that it does what you expect.

I would add, "finding a third-part library", but that was mostly because there were not as many. :) Then again the current glut of libraries is a bit of mixed blessing. I can look for a library that does X and find dozens of them. Very few of them will be mature or do what I want. But that has more to do with the ecosystem than with Python-the-language.
