(formerly pep257)

pydocstyle is a static analysis tool for checking compliance with Python docstring conventions.

pydocstyle supports most of PEP 257 out of the box, but it should not be considered a reference implementation.

pydocstyle supports Python 2.7, 3.3, 3.4, 3.5 and pypy.

pip install pydocstyle

$ pydocstyle test.py

test:75 in public function `init_database`:
