Check out docs for elixir. It's a community where the standard library docs set a high standard of quality that quite a few package developers seem inclined to try to aim for. Heck, the documentation for the Float module even is kind enough to warn you about gotchas in IEEE floating point.

One thing I really like: Unlike in python docs, on all the function calls and most module headings you can click through to the actual elixir source code and see how the functions work under the hood (via the <\> link). You also get this nearly for free when doing docgen on your own modules (it's one line in setup). Also, the HTML is responsive so it's easy to review your own code when on the toilet, if necessary.

And there are python libraries that are horrible offenders. Perhaps it's a matter of taste or experience, but I found the tensor flow docs to be inscrutable and nearly useless
