[TxMt] Re: using python 3.0.1

[Andrei Maxim]

Since I wanted to try out Python anyway, I downloaded the latest Mac package
(3.0.1 to be precise) and installed it on my computer. At the beginning,
`python -V` kept saying it's version 2.5.1 and I couldn't find any
executable called `python3.0` as mentioned above.
The trick is to run the "Update Shell Profile.command" file that was
installed in the /Applications/Python 3.0 folder. It will update your
~/.bash_login so your $PATH will
contain "/Library/Frameworks/Python.framework/Versions/3.0".

Obviously, `python -V` will always say `3.0.1` from now on so you might want
to add it at the end of the path (or at least after /usr/bin/). After that,
here's what I got:

#!/usr/bin/env python
import sys

print(sys.version) #=> 2.5.1 (r251:54863, Jan 13 2009, 10:26:13)

and

#!/usr/bin/env python3.0
import sys

print(sys.version) #=> 3.0.1 (r301:69597, Feb 14 2009, 19:03:52)

Hope that helps.
