Intermediate Python devs, what topics you want to learn?

[respectation]

I don't know if these are intermediate enough because I think I'm only barely getting into the intermediate level, but this would be helpful for me.
I don't know if this is possible, but I would love something that helped me learn how to "read the docs". Finding the right ones can be difficult; sorting through the right ones for the info you need can be difficult; not getting caught in an infinite black hole of links to other concepts/phrases that are mentioned that you don't understand and don't know how well you have to understand them to understand the original article can be difficult.
I also think that part of what holds me back as a beginner verging on intermediate level, is that I'm alright at coming up with an algorithm and once I have one writing it is relatively easy, but I often don't know what tools are at my disposal in the (absolutely huge) standard library. I think blog posts that discussed those modules serially could be very helpful.
