Using Python 2.7 on Windows 7 Good point - subtle difference. I'll have to make that more clear with an autohotkey keyboard macro since I started with 3.3, discovered a lot of stuff is still only for 2.7, and so went back to 2.7, which I'm now using. I still sometimes type input instead of that annoying raw_input and get a weird error. It's a bit confusing since, as a learner, some things have been backported, so there is no simple demarcation and there's already a lot to remember, let alone differences. I'll be glad when this all settles out, but Py 3 has been out awhile and an awful lot seems to only be for 2.7 Thanks to everyone for the useful tips on generators and PyDifferences. They all go into Clipmate ;') Jim _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
