Well it was bit enough that the python community created a brand-new language construct called import __future__ -- something never considered before then and which actually changes the behavior of python unlike any other module. And perhaps I've just felt it more because I was a big proponent of both 3-d graphics as a way to keep python a draw for beginning programmers and also a big fan of scientific simulation. No one had anything near vpython back then. (But ultimately I need to stop mentioning this issue to this vpython list because it's really the Python group which need to get back in sync.) > The new (currently experimental) version of VPython based on wxPython must, > in order to run in a Cocoa environment on the Mac, make the interact loop be > the primary thread, with the user's Python calculations at worst a secondary > thread, which is the opposite of the older VPython, where the > interval-driven rendering thread was secondary to the user's calculations. > By the unusual stratagem of having VPython import the user's program it has > been possible to make this work, and at the same time greatly simplify the > C++ component of VPython by eliminating threading, with additional important > simplification from eliminating essentially all platform-dependent code > thanks to the multiplatform character of wxPython.

I need to analyze this more carefully before commenting further.... mark _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
