Python docstring style checker (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 2.6, 2.7, 3.3, 3.4, 3.5, pypy and pypy3.
