meaning of +1
by Brian Blais Feb. 8, 2007

Feb. 8, 2007

Hello, I am not asking an existential question about the meaning of the integer set, but rather what it means when someone writes in an email on this list, something like: +1 I've never seen this on any other list (other than python lists). Is this just a short hand for "good comment", or is there a deeper meaning or purpose? thanks, bb -- ----------------- bblais(a)bryant.edu http://web.bryant.edu/~bblais

Procedural front end for Zelle's graphics.py
by Peter Drake Feb. 8, 2007

Feb. 8, 2007

Okay, I think I've got it. I will no doubt make changes as the semester wears on, but this should be enough to get me started. Is anyone else using Python procedurally in an intro course, or is what I'm doing here perverse?

I should probably send this to the entire list... On Feb 6, 2007, at 3:04 PM, Peter Drake wrote: > Yes, and you're the third person to have suggested it today.

You're right that on some platforms Tk windows will not "surface." I haven't found a way around this problem yet. I don't understand what you mean by the Console window. Aren't you using IDLE's shell? In general the popping up behind problem is not a big deal since you can just click on the appropriate icon on the task bar to bring it to the front (Windows and Linux). Although this may not work on the Mac... > > 2) Once the main loop starts, you can't enter new commands into the > IDLE shell. > I don't understand this comment. Are you running IDLE in it's normal mode (with a separate subprocess for user code)? I expended a fair amount of effort making my graphics library play nicely with IDLE. The mainloop is completely hidden in the graphics module, and you can continue interacting with any number of graphics objects and/or windows at the IDLE shell. If that's not working for you, make sure to get the newest version of the library. BTW if you are running IDLE in the no-subprocess (-n) mode, then you might want to use the older (non-threaded) version of the library. > 3) It is object-oriented, confusing students with the combination of > regularFunctions() and object.methods(). I'd just as soon avoid this > if possible. I can understand this if that's your goal. My point was to use graphics as a very concrete way to introduce the idea of objects. I don't find that my students have any problems at all with using objects (writing their own classes is another story). > > If anyone can direct me to a way around the first two problems I > could, of course, write wrapper functions to deal with the third. Yes, it would be very easy to wrap flat functions around my graphics library if you restrict yourself to one graphics window. --John > > Peter Drake > Assistant Professor of Computer Science > Lewis & Clark College > http://www.lclark.edu/~drake/ > > On Feb 6, 2007, at 2:23 PM, John Zelle wrote: > > Hi Peter, > > > > Just a quick question for you.

Interactive Tkinter graphics under IDLE
by Peter Drake Feb. 7, 2007

Feb. 7, 2007

Okay, so I've got a simple system worked up that allows students (these are "CS0" non-CS-majors) to manipulate objects with commands in the IDLE command window. The file is attached. The next thing I'd like to do is define a function mouse() that starts the main loop, waits for a mouse click, stops the main loop, and returns the coordinates of the mouse click. Any suggestions?

PyCon Activities
by Michael Tobis Feb. 6, 2007

Feb. 6, 2007

Happy February y'all. So, what are we planning to do at PyCon in the edu-sig? It's linked from the PyCon 07 front page but doesn't seem to go anywhere. Is there some organizing activity that I don't know about? Any ideas about rooms, times, presentations? Another dinner? mt

I never met Arthur. I have only read his frequent contributions to this list. Yet I am deeply saddened by news of his passing. His words were thought-provoking, his ideas challenging (and he sometimes even kept Kirby at bay...). I will miss him a great deal. --------------------------------- We won't tell.

Re: [Edu-sig] [PyCON-Organizers] Interest in Newby lecture at PyC on?
by Michael Tobis Feb. 1, 2007

OK. So I think people should not need to be registered for the conference to attend. Is that possible? I imagine Python 101 is for professionals learning Python as an nth language. I don't intend to compete with that. I would like to call the presentation "Python as a First Language", and would like attendees to have a working copy of Idle on a laptop. The intended audience will be in town (locals or accompanying family) but is unlikely to pony up for the conference. If it is OK with you all and the hotel I will be happy to proceed on the basis that it is free of charge and doesn't require conference registration. Alternatively I could offer sort of a dress rehearsal, and edu-sig types can attend but it would probably be of little interest to other badge carrying conference attendees. This would be much shorter. My current plan is to be arriving Friday and leaving Sunday so I'd much prefer early on Saturday evening.
