在Python中有很多很好的工具来生成字符串文档(docstring),比如说: epydoc、doxygen、sphinx,但始终觉得pydoc还是不错的工具,用法非常简单,功能也算不错,本文主要介绍pydoc.

pydoc是Python自带的模块,主要用于从python模块中自动生成文档,这些文档可以基于文本呈现的、也可以生成WEB 页面的,还可以在服务器上以浏览器的方式呈现!

用法

Windows下:

D:\>python -m pydoc <modulename>   # 比如说: python -m pydoc math  

-m参数:Python以脚本的方法运行模块


Linux/Unix下:

$ pydoc <modulename>               # 比如说: pydoc 
帮助
$ pydoc -h
pydoc - the Python documentation tool


pydoc <name> ...
    Show text documentation on something.  <name> may be the name of a
    Python keyword, topic, function, module, or package, or a dotted
    reference to a class or function within a module or module in a
    package.  If <name> contains a '/', it is used as the path to a
    Python source file to document. If name is 'keywords', 'topics',
    or 'modules', a listing of these things is displayed.


pydoc -k <keyword>
    Search for a keyword in the synopsis lines of all available modules.


pydoc -p <port>
    Start an HTTP server on the given port on the local machine.


pydoc -w <name> ...
    Write out the HTML documentation for a module to a file in the current
    directory.  If <name> contains a '/', it is treated as a filename; if
    it names a directory, documentation is written for all the contents.
参数 -p】在本地机器上,按照给定的端口启动HTTP,

D:\>python -m pydoc -p 1234 #比如说: 端口为1234

pydoc server ready at http://localhost:1234/

pydoc server stopped

在IE中输入:http://localhost:1234/,效果如图:

参数 -k】在所有可用的模块中按关键字搜索

$ pydoc -k xml.sax
xml.sax (package) - Simple API for XML (SAX) implementation for Python.
xml.sax._exceptions - Different kinds of SAX Exceptions
xml.sax.expatreader - SAX driver for the pyexpat C module.  This driver works with
xml.sax.handler - This module contains the core classes of version  2.0 of SAX for Python.
xml.sax.saxutils - A library of useful helper classes to the SAX classes, for the
xml.sax.xmlreader - An XML Reader is the SAX 2 name for an XML parser. XML Parsers
参数 -w】将指定模块的文本字符串生成HTML格式

比如说,在Window下面,执行下面命令:

D:\Learn\Python>python -m pydoc math -w math.html  # math是模块名,-w:写
那么在D:\Learn\Python目录下会生成math.html文件,显示如下:

因为是自带的模块,所以右上角显示(built-in)字样

例子】自写的模块my_doc.py

'''
Showoff features of Pydoc module
This is easy module to demonstrate docstrings
'''
__authors__  = 'Alice & Fred'
__version__  = 'version 1.10'
__license__  = 'Copyright...'

class MyClass:
    '''
    Demonstrate Class Docstrings
    
    '''
    def __init__(self, spam=1, eggs=2):
        '''
        Set the default attributevalues only
        Keyword arguments:
        spam - a processed meat product
        eggs - a fine breakfast for lumberjacks
        '''
        self.spam = spam
        self.eggs = eggs

def square(x):
    '''
    Square of the param <x>
    '''
    return x * x
执行命令:
D:\Learn\Python> python -m pydoc my_doc
执行结果:
