The first step is to install Python if you haven't already. Python is available from the Python project page at http://sourceforge.net/projects/python. Click on the link corresponding to your platform, and follow the instructions described there. Unlike earlier versions of numarray, version 0.5 and later require Python version 2.2.2 at a minimum. When installed, starting Python by typing python at the shell or double-clicking on the Python interpreter should give a prompt such as:
Python 2.2 (#1, Mar 15 2002, 14:38:30) [C] on linux2 Type "help", "copyright", "credits" or "license" for more information.
