Naive users won't have PYTHONPATH or any other Python environment variables setup. Really, if you know that you are going to run Python 3 instead of Python 2 or vice-versa it's easy enough to run

You don't even know that you're going to run python. I have 40 python scripts in my /usr/bin directory.

. py3env.sh or . py2env.sh in order to setup your shell environment, much like you typically do when using virtual Python installations or work on different projects that require different setups.

No, thanks. I'd rather setup my shell environment in ~/.zshrc, once.

If you just want to separate Python 2 and 3 files, use the user site-packages dir which includes the Python version.

Both the bzr and mercurial wiki recommend setting PYTHONPATH in order to install those programs in a user's home directory. There are still people running python <2.6.
