"""Example docstrings.
This module demonstrates documentation as specified by the `Google Python
Style Guide`_. Docstrings may extend over multiple lines. Sections are created
with 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.py
Section breaks are created by resuming unindented text. Section breaks
are also implicitly created anytime a new section starts.
"""# 不推荐的写法(不要写函数原型等废话)
