Sounds like you got it working, but if you are curious as to why "sys.exit()" doesn't work, it sounds like you haven't imported the sys module. To do this simply place "import sys" at the top of the file. Hope this helps.
That's probably because before python 3.3 virtual environments were a third party solution and not part of the standard library. When we finally get good python 3 tutorials maybe they'll include venv.

I'm extremely tempted to try typing import antigravity into my code now :D
Actually, do try it. It links you to that comic.

That should be in every tutorial even before the hello world.
Tutorials are often lacking. For instance, none seems to deal virtual environments, one of the most important concepts of python.
