How do I run a python interpreter in Emacs?

python emacs interpreter

I just downloaded GNU emacs23.4, and I already have python3.2 installed in Windows7.

I have been using Python IDLE to edit python files.

The problem is that I can edit python files with Emacs but I do not know how to run python interpreter in Emacs. When i click on "switch to interpreter", then it says "Searching for program: no such file or directory, python"

Someone says i need to make some change on .emacs file, but i do not know where to look for.

And I am very unexperienced and just started to learn programming. I am not familiar with commonly used terminologies. I have been searching for solutions but most of the articles i find on the Internet only confuse me.

so the questions are:

  1. how do i run python interpreter in Emacs?
  2. are there different kind of python interpreter? if so, why do they have different interpreters for one language?

Place this in your .emacs to let emacs know where is your python interpretor

 (setq python-shell-interpreter "path\to\your\python3.2")

To learn about.emacs you can read about it in Emacs itself.(Emacs comes with good info manuals and info mode to help to read that manual).

press the following in emacs

M-: (info "(Emacs)Init file") RET.
