  what is the situation with python 2.6 vs 3.1 in f12?  IIRC, f12
will still use python 2.6 internally, but if someone wanted to

install python 3.1 and let them use that for their programming,
while leaving the OS to continue using 2.6?  i can't see that
causing any problems as long as the programmers explicitly refer
to the python 3.1 program for their coding, but i just want to be
sure.

  besides, if someone was looking to learn to program in python, it
would seem to make sense to just start with 3.1, no?
There is a lot of work being done for Fedora 13

https://fedoraproject.org/wiki/Features/Python3F13

  but just *unofficially*, is there any issue with installing Python 3
in F12 (or even F11, as i'm trying to do now)?  as it is, i've
downloaded the Python-3.1.1 tarball, unloaded it and -- following
along in the README -- just did:

  $ ./configure
  $ make
  $ make test

after which the README claims that running "make install" will install
this as "python3", which would *seem* to allow it to co-exist
peacefully on this system, and programmers could explicitly invoke
"python3" if they wished.

  is there any flaw in my reasoning?

It should be installing to /usr/local. If so,it's almostall good - just watch for $PATH settings. Probably, you don't want /usr/local directories ahead of not-local directories for the normal case.

Alternatively, just use one of your spare lappies for a test system.

Or a virtual system.
