    ...read the Python tutorial, seen various Python programs and liked the language very much for its simplicity, object oriented nature, dynamic data typing, and large standard library. Starting with a few simple Python scripts using VTK, I was able to get my colleagues up and running fairly quickly with a few custom CFD visualization scripts. At this time I was still learning Python and Tkinter (the GUI toolkit used in MayaVi) and created a GUI based tool called VTK-CFD in June 2000. This went thr...

  • Glue It All Together With Python

    ...reads header files containing function and method prototypes and automatically generates the necessary type conversion and error checking code. In situations where the underlying code (usually C code) doesn't use an object-oriented model, the glue extension can in turn be wrapped in a Python module that defines a proper class hierarchy, while delegating the performance critical operations to the C code. Using Python, better applications can be developed because different kinds of pro...

    ...reading, writing and arithmetic. We really mean computer programming--not just computer use (which is already being taught). The Logo project [Papert][Logo], for example, has shown that young children can benefit from a computing education. Of course, most children won't grow up to be skilled application developers, just as most people don't become professional authors--but reading and writing skills are useful for everyone, and so (in our vision) will be general programming skills. For t...

    ...read the description and build the in-memory structures on which the game would run. This would have been a fairly large effort, and would have required me to formalize all of the structures that could have appeared in a world. It also would have meant a longer delay before I had something that Nat could actually use. On the other hand, I could have simply used Python statements to construct the structures directly. This would have been tedious and error-prone. As a handy middle ground, I used P...

"Python's ease of maintenance is a huge deal for any company that has any significant amount of staff turnover at all," says Friedrich. The team had already developed a moderately large number of C++ libraries. Because of Python's easy interface to the outside world, USA was able to retain these libraries. "We wrote a grammar-based tool that automatically interf...

New command line option "-x" to skip the first line of the script; handy to make executable scripts on non-Unix platforms. In importdl.c, add the RTLD_GLOBAL to the dlopen() flags.
