Example Google Style Python Docstrings

# -*- coding: utf-8 -*-"""Example Google style docstrings.This module demonstrates documentation as specified by the `Google PythonStyle Guide`_. Docstrings may extend over multiple lines. Sections are createdwith a section header and a colon followed by a block of indented text.Example:    Examples can be given using either the ``Example`` or ``Examples``    sections. Sections support any reStructuredText formatting, including    literal blocks::        $ python example_google.pySection breaks are created by resuming unindented text. Section breaksare also implicitly created anytime a new section starts.Attributes:    module_level_variable1 (int): Module level variables may be documented in        either the ``Attributes`` section of the module docstring, or in an        inline docstring immediately following the variable.        Either form is acceptable, but the two should not be mixed. Choose        one convention to document module level variables and be consistent        with it.Todo:    * For module TODOs    * You have to also use ``sphinx.ext.todo`` extension.. _Google Python Style Guide:   http://google.github.io/styleguide/pyguide.html"""module_level_variable1=12345module_level_variable2=98765"""int: Module level variable documented inline.The docstring may span multiple lines.
