title: How can I edit PYTHONPATH on a Mac?
body: <p>How can I permanently change the PYTHONPATH on a mac? I've tried editing .bash_profile, but when I use <code>print sys.path</code> in a file it gives a huge list of different URLs than the .bash_profile. In Terminal when I type <code>echo $PYTHONPATH</code> it shows a blank line. I don't want to use sys.path.append('...') because then I have to put that in every file.</p>
