 From *inside* the Python interpreter:

py> import sys
py> help(sys)
Help on built-in module sys:

NAME
     sys

FILE
     (built-in)
[...lots of info...]

py> help("sys")
Help on built-in module sys:
[...same info...]


 From the system command line (shell, command prompt, DOS box...), assuming  
you're using 2.5 or later:

c:\temp>python -m pydoc sys
Help on built-in module sys:
[...same info...]


C:\TEMP>python -m pydoc
pydoc - the Python documentation tool

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

pydoc.py -p <port>
     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 <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.


Try the -g option; it lets you search for the relevant documentation and  
show it on your favorite web browser (locally).

Depending on how you installed Python, you may find a 'pydoc' or  
'pydocgui' script somewhere in your Python directory.
