Pyreverse

Pyreverse is a module inside Pylint, which generates UML diagrams out of Python code.

Create a PlantUML class diagram

$ pyreverse -o plantuml --module-names yes -s 1 -d my/output/dir \
path/to/module_A.py path/to/module_B.py ... && \
sed -i "" "s/set namespaceSeparator none/set namespaceSeparator ./g" my/output/dir/classes.plantuml

-o plantuml

Generate the UML diagram in PlantUML format (*.plantuml)

--module-names yes

Embed classes inside the module, they are located in

-s 1

Show associations up to level 1 (direct associations)

-d my/output/dir

The output path for the diagram files

sed -i "" "s/set namespaceSeparator none/set namespaceSeparator ./g" my/output/dir/classes.plantuml

Replace te namespace separator from none to ., which effectively uses the modules as namespaces, which puts classes of the same module inside a frame
