Coding Style introduced by
This module should have a docstring.

The coding style of this project requires that you add a docstring to this code element. Below, you find an example for methods:

class SomeClass:
    def some_method(self):
        """Do x and return foo."""

If you would like to know more about docstrings, we recommend to read PEP-257: Docstring Conventions.
