Install a working Python Environment

Enthought Scientific Computing Solutions produce a bundled Python installer that installs compatible versions of Python and assorted tools.  It can save lots of time  in sorting out which versions of other packages to install (NumPy etc.)  Academic users can install the entire package at no cost - just go to the downloads page and select "Downloads", then scroll to the bottom of the page to find out how to download the academic version.  You will need an academic e-mail address.
