When I start introducing Python I use this chart [1]:
Five Dimensions of Python:
- Level 0: core syntax with keywords & punctuation, indentation (import,
if...)
- Level 1: a large set of built-ins (e.g. print)
- Level 2: special names with the double underlines
- Level 3: Standard

instructors. I'm scheduled to start a new round

Fall. As is common with community colleges there is a lot of 'training'
for particular tools and languages to meet immediate needs of local
employers. As a representative of the big, research university in t
Hi David,
I teach at DePaul university where we now use Python in multiple
classes. The way we got it in was not by proposing Python in
substitution to Java or C++. I tried it and that failed for the same
reasons you mention. I got it in by starting to use Python in
algorithms classes inst
Thanks Dave --
A wonderful question that points to the great cultural divide
between compile-time versus runtime error trappers.
The compile timers flirt with the notion that somehow the
compiling step might actually constitute a *mathematical proof*
that the program is correct (if only the langu
I talked with the CIS department chairman and one of the faculty about the
possibility of teaching Python at our community college, and they weren't
interested. (Oh No, not another language ... ) Also, the lack of declarations
was a show-stopper.
I encountered this same objection from one o

This leads to a series of deprecated links, some several months old, and no
clear guidance as to what a student should install. This website is a mess!!

Our mandelbrot demo is working nicely, thanks to all the help I've gotten from
folks on this list. We are using only the weave package, not the full SciPy

I got scipy.weave working in my Mandelbrot demo in Python2.5 under Cygwin, and
the speed improvement is comparable to my hand-coded extension module.

David,
For output graphics, you might want to have a look at Pygame. It is a wrapper
for the SDL library. It has functionality for creating graphics windows,
drawing, sprites, etc. But what m
