Configure your Mac so that when you double-click a .py file, it opens Sublime.

Configure Python2 and Python3 Build Systems

Configure Sublime so that you can switch between Python2 and Python3 for builds. When you set this, you can press command-B (on a Mac) in the editor and it will run your program. (Instructions inspired by this page, which has great screen shots.)

1. First, make sure Sublime is running the correct Python2 by default. 1. In the Sublime Text 2 app, go to Preferences > Browse Packages > Python. 2. Edit the Python.sublime-build file. 3. Comment out this line: //"cmd": ["/usr/local/bin/python", "-u", "$file"], (Add the //.) 4. Add this line: "cmd": ["/usr/bin/env", "python", "-u", "$file"], (Don't forget the comma.) 5. Save the file, open a simple Python2 program, and see if command-B works.
2. Now, copy the contents of the preference file you used in the prior step. 1. In the Sublime Text 2 app, go to Tools > Build System > New Build System... 2. Paste into the blank file. 3. Change the line to be "cmd": ["/usr/bin/env", "python3", "-u", "$file"], 4. Save as Python3. 5. If you ever need to edit this file again, you'll find it in ~/Library/Application Support/Sublime Text 2/Packages/User.
3. When you are working in Python, in the Sublime app look under Tools > Build System and you should be able to selected between Python and Python3.
