I've used Python sparingly in the past for tooling and helper apps and am now picking it up in a more serious way as I'm working on a Flask API app. I've been reading lots of instructional materials and the one thing that I find lacking across the board is coverage of the toolchain and it's edge cases. For starters, Macs only come with Python 2.X, tell me about installing 3.X and some of the walls I might run into in the process. Having used other package managers, pip is easy to pick up but you might get stuck if you forget you need to use pip3 instead. virtualenv is something that could use a more thorough explanation in almost everything I've read, but I'm also now seeing everyone shift to using pipenv and sorting this out yourself is not easy to newcomers (I haven't seen a text yet that discusses it other than packages using it in their install copy and paste and the pipenv site itself). The small things that seem obvious to seasoned devs are really what I'm looking for, especially in an accelerated course.
This applies almost equally to most language reference material I've come across but I'm asking politely, please spend more time on the toolchain.
