Running Python interpreter in Emacs

[Rex Eastbourne]

I went to My Computer | Properties | Advanced | Environment Variables
and added c:\program files\python24 to both the PYTHONPATH and Path
variables. Still no luck. I don't know whether the path I'm talking
about is the same as the $PATH you referred to, or whether I'm supposed
to put python.exe explicitly somewhere; could someone refer me to a
place where I can read about these things?

Thanks!

Rex
