Python中本身带有很多实用的工具,如pydoc。pydoc模块主要用来从Python模块中提取信息并生成文档。
在Windows和Linux下的使用方法有些区别。
python -m pydoc
如:
C:\>python -m pydoc module_test
NB:module_test是自定义的模块,不要添加文件后缀。
pydoc
如:
$ pydoc module_test
$ 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
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 <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.

显示文档,
可以是相查询的任何东西。如关键字、函数、模块、包等等。
C:\>python -m pydoc print
Help on built-in function print in module builtins:
print(...)
print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=False)
Prints the values to a stream, or to sys.stdout by default.
Optional keyword arguments:
file: a file-like object (stream); defaults to the current sys.stdout.
sep: string inserted between values, default a space.
end: string appended after the last value, default a newline.
flush: whether to forcibly flush the stream.
C:\>python -m pydoc random
Help on module random:

在当前主机启用HTTP服务,使用指定的端口。
C:\>python -m pydoc -p 53241
Server ready at http://localhost:53241/
Server commands: [b]rowser, [q]uit
server> b

这时可以点击来跟踪链接进行查看相应的文档。
生成HTML文档。
首先编写一个模块,此外为class_test.py
:
"""
A simple test.
"""
if __name__ == "__main__":
print("hello")
然后执行如下:
C:\>python -m pydoc -w class_test
wrote class_test.html
此时在C盘根目录下生成了class_test.html
文件,就可以在浏览器中进行查看了。
