Help with Python Programming

I am completely new to programming, so i decided to try out Python, i downloaded the Python 3.1 package, my computer currently has python 2.5. When i do the Updateshell.command. It says that 3.1 has been installed and all but then when i look in terminal it still says 2.5 is the current python release i have. and none of the Programs i write in IDLE will work because i dont have the latest version. ***? how do you update to python 3.1?

It's probably installed; check in the following directory: /Library/Frameworks/Python.framework/Versions/. For instance, I have versions 2.6 and 3.0 located here along with the system default 2.5 which is located at /System/Library/Frameworks/Python.framework/Versions/.

Are you trying to use the IDLE version that came with Python 3.1? If so, it should work. What errors are you getting when running the update shell script?
