If I understand your question: you're probably better off putting a shebang line in all of the files that you intend to run directly. Use "/usr/bin/env python2" for your Python 2 scripts, "/usr/bin/env python3" for your Python 3 scripts, and "/usr/bin/env python" for scripts that can run under either interpreter. You can also be more version-specific if you need to; use "python2.7", "python3.3", etc. as necessary. That way, you can invoke the script directly and the right interpreter will run it. If you're specifying the interpreter in your command (by calling "python <scriptname>.py", etc), the shebang won't mean anything anyway. -- Zach
