Python文檔生成工具pydoc使用介紹

   這篇文章主要介紹了Python文檔生成工具pydoc使用介紹,本文講解了基本用法、獲取幫助的方法、生成的文檔效果圖等內容,需要的朋友可以參考下

  在Python中有很多很好的工具來生成字符串文檔(docstring),比如說: epydoc、doxygen、sphinx,但始終覺得pydoc還是不錯的工具,用法非常簡單,功能也算不錯,本文主要介紹pydoc.

  pydoc是Python自帶的模塊,主要用於從python模塊中自動生成文檔,這些文檔可以基於文本呈現的、也可以生成WEB 頁面的,還可以在服務器上以浏覽器的方式呈現!

  【用法】

  Windows下:

   代碼如下:

  D:>python -m pydoc # 比如說: python -m pydoc math

  -m參數:Python以腳本的方法運行模塊

  Linux/Unix下:

   代碼如下:

  $ pydoc # 比如說: pydoc

  【幫助】

  代碼如下:

  $ pydoc -h

  pydoc - the Python documentation tool

  pydoc ...

  Show text documentation on something. 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 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

  Search for a keyword in the synopsis lines of all available modules.

  pydoc -p

  Start an HTTP server on the given port on the local machine.

  pydoc -w ...

  Write out the HTML documentation for a module to a file in the current

  directory. If contains a '/', it is treated as a filename; if

  it names a directory, documentation is written for all the contents.

  【參數 -p】在本地機器上,按照給定的端口啟動HTTP,

   代碼如下:

  D:>python -m pydoc -p 1234 #比如說: 端口為1234

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

  pydoc server stopped

  在IE中輸入:http://localhost:1234/,效果如圖:

  【參數 -k】在所有可用的模塊中按關鍵字搜索

   代碼如下:

  $ 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

  【參數 -w】將指定模塊的文本字符串生成HTML格式

  比如說,在Window下面,執行下面命令:

   代碼如下:

  D:LearnPython>python -m pydoc math -w math.html # math是模塊名,-w:寫

  那麼在D:LearnPython目錄下會生成math.html文件,顯示如下:

  因為是自帶的模塊,所以右上角顯示(built-in)字樣

  【例子】自寫的模塊my_doc.py

   代碼如下:

  '''''

  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

  '''

  return x * x

  執行命令:

   代碼如下:

  D:LearnPython> python -m pydoc my_doc

  執行結果:

  代碼如下:

  Help on module my_doc:

  NAME
