Hello. Please tell me whether this feature request is sane (and not done before) for python so it can be posted to the python-dev mailing list. I should say first that I am not a professional programmer with too much technical knowledge.
I would like to have something like the "option explicit" statement in Visual Basic which turns on C-like checking for declaration of variables. This is highly helpful for people who are coming from C/C+ +, for people who are learning programming using Python, and even professionals, since this helps prevent typo errors like: sunlognitude = sunlongitude + 180.0 where the user has inadvertantly typed "g" before "n" and will later wonder why his application is not working as expected. -- http://mail.python.org/mailman/listinfo/python-list
