Python documentation here

Example

$python -m pydoc pydoc

Talk about eating your own dogfood! This is exactly like using the help() function in the python command line interpreter… except accessible from your shell prompt…. but wait!

It’ gets better! Not only does it make julian fries ( may not for any implementation ) but it’s got a few versatile little secrets

$ python -m pydoc
pydoc - the Python documentation tool

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

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

pydoc.py -g
    Pop up a graphical interface for finding and serving documentation.

pydoc.py -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.

Now the graphical interface isn’t anything to write home about, but the -p option provides a no thrills web interface to
almost everything accessible to your python interpreter. This can make it slightly easier to troll through foreign modules
looking for undocumented sub modules and classes… or having an accessible reference doc for properly managed modules
