The first thing I got while trying to run a python3 prompt few days ago, was an error. python3 tried to read my $PYTHONSTARTUP file, which used print statements. people will have to run both python 2 and python 3 code at the same time. Using different environment variables will make this easier. What do you need to do in the PYTHONSTARTUP file? Ten years of Python programming, and I didn't even know it existed. :-)

hehe. tab completion:

-- mode: python --
