Re: [Tutor] Lamdas and locality
Thanks for your answer and your workaround! There's always something to learn about lambdas and variable scope in Python ;) I'm sorry I didn't delete the quoted Tutor Digest part, it was a stupid mistake :( cheers, Michael ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

forth and postscript are both rpn notated languages. stack oriented languages include also other stuff, e.g. the jvm assembly language. (Although the security verifier does place rather strict limitations on the allowed stuff) but that's where the common things end. forth is a lowlevel language that manipulates memory directly, it's untyped too ;) postscript otoh is a typed language with comparable safety to Python.

Postscript borrows heavily from Forth, I think.

The CPython virtual machine is also a stack-based language.

[Tutor] How does datetime.now() get timezone?
Hi all, this is maybe more of a Linux question or about how Python plays together with the OS: I have a virtual server on which I installed Ubuntu Dapper LTS with a minimal install plus the things I needed. If I do from datetime import datetime t = datetime.now() there, 't' is a naive datetme object, i.e. t.tzinfo is None. If I do the same on my developing machine, which has also Ubuntu Dapper, I get a timezone-aware datatime object. What do I have to do to set the timezone so that Python can recognize it? I already installed the 'locales' package, ran 'tzconfig' and installed timezoneconf and ran that, but to no avail.

[Tutor] basic plotting questions (pyplot vs matplotlib, etc)
I'd like to learn to use basic plotting in a wxPython GUI app, with plots embedded in the GUI. Some questions about this: 1) Of pyplot or matplotlib, which might you recommend? My needs are: - embedded plots in GUI (either can AFAIK) - basic point/line/pie/bar graphs, regression lines, clickable points. (not sure if pyplot does regression lines or pie charts.) - get the datapoints from a SQLite database queries - reasonably do-able for a determined beginner programmer (me) - not too memory intensive/app-bloating Clearly matplotlib can do it all but I'm unsure if it is overkill for my needs? 2) What does "DC" mean? As in wxDC? 3) I'd like to try a simple embedded plot in pyplot to get started. Boa Constructor will place a plot canvas to start, but I'm having trouble wading through the code of the pyplot example from the wxPython demo. Could someone help me with the barest bones of a simple line plot on a canvas? Just x = (1,2,3,4,5), y = (2,4,6,8,10) sort of thing.

I'm guessing, but based on my previous experience of other GUIs, it will be a Device Context. A DC is a concept which tries to abstract the hardware used for graphics so that you can create the same graphic and display it on a screen or on a printer with minimal change. You just pass in the appropriate DC to the graphics functions. This is good for WYSIWYG type work, but can mean that "simple" priniting (eg text) is much more difficult than would normally be the case!
