Thanks very much for all replies I received for my question. It's clearer now. By the way, for Windows users, I do recommend Microsoft's PTVS (Python Tools for Visual Studio). It's an excellent IDE and free if you use the Express Edition of Visual Studio. David -- https://mail.python.org/mailman/listinfo/python-list
