Re: building a small calculator

Once again, a rough first approximation.) I'd second the recommendation you received to check out the Tutor list -- both lists are friendly, but Tutor is perhaps better geared to the level of explanation that you might find most helpful in these early stages. Best, Brian vdB -- http:

your code worked on 2.2.2; I've no idea. The docs do seem to indicate that there were a number of changes at 2.2, though. Best, Brian vdB -- http://mail.python.org/mailman/listinfo/python-list

Proceed with caution." It isn't really private as Python lets you get to pretty much anything. It is a strong signal, though. HTH, Brian vdB -- http://mail.python.org/mailman/listinfo/python-list
