To add some clarification to what everyone's already said: OSX comes with a Python install by default, but it's not the latest and greatest. You can make a secondary install using the disk image from python.org; this will install alongside the standard Python install, so both are available.
Once you have installed a new python, you can go to the commandline and type "which python". This will tell you the path to the Python executable you are currently using whenever you type "python" on the commandline. If it isn't the python you want, you can do "which -a python" to get a list of all of your options. For example: % which python /usr/bin/python % which -a python /usr/bin/python /usr/local/bin/python This says that by default I will run the python in /usr/bin (which is the default installed Python in OSX), but that there is another python in /usr/local/bin which I can also run (which is the one that I installed myself). Good luck with your class! -Chris On Wed, Jan 12, 2011 at 9:30 PM, Bill Janssen <jans...@parc.com> wrote: > Macs come with Python pre-installed.
