What is the best way to install python 2 on OS X?

My colleague wants to use my python 2 code on his OS X machine (10.6). My code imports several built-in python packages, including Tkinter and shelve, and also uses third-party packages including numpy, scipy, matplotlib and ipython.

I ran into some problems with the OS X built-in python. (IDLE does not work, for example *). I suspect that I should install a newer version of python and a different version of Tk .

My questions:

  • Will there be two different versions of python / Tk on the same computer problem?

  • I would like to associate the terminal commands "python", "ipython" and "easy_install" with a newer version of python. How should I do it?

  • When I install third-party packages such as numpy using a .dmg file , how do I control which version of python numpy installs in?

  • Is there a better way to do this?

If this process is going well, I would consider adding OS X instructions to my code documentation, so I would like to reduce this process to the simplest, most general approach.

I'm not sure what will happen when you install from a .dmg file. I believe that he will just use any version python.
