  • Bugs in Python 2.3

    Bugs in Python 2.3 IDLE now executes code in a separate process. To communicate between the main process and executing processes, IDLE opens a socket to 127.0.0.1 (the local machine).

This problem only occurs if you run a firewall on the same machine as IDLE. IDLE fails to start on Windows if installed to a directory with a space (e.g. C:\Program...

Since Python is a scripting language, it was the natural choice for an extension language for MayaVi. As a result, MayaVi isn't just written in Python but can also be scripted by end users working in Python, in order to extend it with additional useful functionality. I'm not a software developer or a computer scientist. Neither am I a graphics expert. While...
