Default location of python on OS X

[Stephen_B]

I've installed the latest 2.5 python today from python.org, and I
think it ended up in "/Applications/MacPython 2.5".

I also have a "/Applications/MacPython 2.4" and a "/Applications/
MacPython-2.4". Can I delete these, or did one of them come with
Leopard?

I still have a "/Library/Python/2.3" and a "/Library/Python/2.5".

Thanks.

Stephen
