关于Python docstring几种主流风格

本文主要是介绍关于Python docstring几种主流风格,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

今天在整理Python文档的时候,发现除了目前在用的如下格式外,还有很多种。就简单整理一下。

def foo(bar: str) -> str:
    """
    foo function
    
    :param str bar: bar
    :return: return bar
    :rtype: str
    """
    return bar

目前流行的格式有如下几种,我之前用的属于reST,是目前最广泛的一种方式,是Sphinx原生支持的格式。还有Epytext,好像是从Java那来的。如果你在Swagger Codegen上生成过Python 代码会发现其中的格式也是reST。还有一种比较流行的是Google自家用的格式,貌似更简洁一些,格式可以参考这里。Numpy团队在Google的基础上搞了一套格式,参考这里

Epytext

"""
This is a javadoc style.

@param param1: this is a first param
@param param2: this is a second param
@return: this is a description of what is returned
@raise keyError: raises an exception
"""

reST

"""
This is a reST style.

:param param1: this is a first param
:param param2: this is a second param
:returns: this is a description of what is returned
:raises keyError: raises an exception
"""

Google

"""
This is an example of Google style.

Args:
    param1: This is the first param.
    param2: This is a second param.

Returns:
    This is a description of what is returned.

Raises:
    KeyError: Raises an exception.
"""

Numpydoc

"""
My numpydoc description of a kind
of very exhautive numpydoc format docstring.

Parameters
----------
first : array_like
    the 1st param name `first`
second :
    the 2nd param
third : {'value', 'other'}, optional
    the 3rd param, by default 'value'

Returns
-------
string
    a value in a string

Raises
------
KeyError
    when a key error
OtherError
    when an other error
"""

最后,想抱Google的大腿了,但是工作量巨大。。。后悔没在一开始就选好T T
