flake8-empty-init-modules

flake8 plugin that disallows code in __init__.py modules.

installation

python -m pip install flake8-empty-init-modules

checks

EIM001

Disallows all code in any __init__.py module.

EIM002

Allows imports and assignment to __all__ in __init__.py modules, but nothing else.

This check is disabled by default. To use this check instead of EIM001 add the following to your setup.cfg

[flake8]
ignore = EIM001
enable-extensions=EIM002

rationale

Code in __init__.py modules is often unwanted because:

• it runs at import-time - this can cause surprising import-time side-effects
• these modules are often empty, so code there is easily missed

The relaxed version of this check allows convenience imports in __init__.py modules without allowing 'real' code to hide out there.
