Invoking python from emacs

[Jason Taylor]

I want to use emacs to edit python code. I am working on Windows 2000,
using GNU Emacs 20.7.1 and Python 2.2.1.  I have loaded mode-python.el
and it adds the menus IM-Python and Python.

How do I tell emacs where python is? When I try to execute the buffer
(C-c C-c)I get the following message:

    'python' is not recognized as an internal or external command,
    operable program or batch file.
