Tool that checks that there are no __init__.py in your modules.
It's opinionated tool, sometimes __init__.py files are useful. But often if you use them you end up in a circular import error mess.
Some packages (eg mypy) works better with __init__.py, for this case you can pass --allow-empty parameter.
# install
pip install no_init
# usage (you can also use python -m no_init)
no_init my_module
# require empty __init__.py for each all submodules (recursively)
no_init --require-empty my_module
# require __version__ variable in my_module/__init__.py (no other content is allowed)
no_init --require-version my_module
