Sometimes I would like to look at class diagrams, and not scroll through my code.
What I just learned: pylint actually ships with pyreverse to do just that:
pyreverse -o <FORMAT> my_package[.my_module] -d <OUTPUT_DIRECTORY>creates class diagrams in dot, PlantUML puml and MermaidJS mmd (or anything graphviz can handle). For a quick look, it is e.g. possible to create a skeleton with pyreverse, copy this (cat classes.mmd | pbcopy) into mermaid.live and export what you want to show.
