Google search heavily focuses on the last page that users visit for a query. And python documentation is hard for most novice programmers to understand.

My guess would be that engineers first go to documentation, don't understand it, go to low-quality-content-farms which answer their questions in natural language. It's low quality but it's enough for novice use cases such as python endsWith.

And this leads to a big reduction in Google's ranking of python docs.

TLDR : most novice programmers don't/can't read docs.
