It's very simple, made for beginners, and fast enough for simple plots (just turn off the tracer). If you intend to introduce the class to GUI's at some point I believe turtle is built on the Tkinter canvas widget, which may be suitable as well. However, if you're teaching scientific programming to more technically advanced users you might be better off using matplotlib/ipython. That will get you a matlab-like enviroment with many advanced capabilities. -- David -- http://mail.python.org/mailman/listinfo/python-list

It'll even let you work with numeric arrays and then put those arrays on screen. Sign up to the pygame users list to ask more questions - they're always a helpful, friendly bunch.

You can find information on his book and the graphics.py file he uses at: http://mcsp.wartburg.edu/zelle/python/ It certainly meets your easy to learn and Python requirements - and of course speed is subjective so it may or may not be fast enough for you.

Simple but fast 2D lib for drawing pixels
Hello, we want to teach absolute programming newbies a first language, so they can start programming simple scientific models. We thought Python would make a good choice for a first language; but where pretty stumped when we found out that there is no simple way to draw pixels to a screen. (This is needed for fractals, agent-based models etc -> like Conways Game of Life) Our requirements: -) easy to learn (newbs!) -) not too slow (after all, the models should simulate something) -) python :-) Any ideas?
