    ...packages from source and configure the packaging system. The IceBridge console running under Mac OS X Zoom in Speed, Scalability and Stability One of our concerns was the speed of our system. Python proved to be "fast enough" for our uses as the most processor-intensive stuff is already written in C (GUI toolkit, GUID generators, numeric manipulations, etc.). We only had to write, in Python, our custom RPC protocol, because XML-RPC (and it's Python implementation) proved to be too...

  • Python Success Stories

    Python Success Stories Background MayaVi is an open source scientific data visualization tool written entirely in Python. I started work on MayaVi in 2000. At that time, a few colleagues of mine needed to visualize their computational fluid dynamics (CFD) data but the only suitable tools available were commercial, closed source programs that were prohibitively expensive. We looked at some open source tools as alternatives. OpenDX had just been released to the public and at that time was har...

    ...packages support development in many application domains. An unsurprising syntax and the widespread and consistent use of a few basic concepts, like namespaces, help to make Python code readable and maintainable. Extensive and easy to use introspection facilities make Python easy to learn interactively by discovering its capabilities, including documentation, from the command prompt. Python is readily extensible in C or C++, so it is easy to incorporate non-Python modules into an application. ...

PEP 245 - Python Interface Syntax - Pelletier Jim Fulton has said that this PEP was premature. I agree. It introduces a new keyword, 'interface', and I'm not yet convinced that that is needed. On the other hand, the way this is currently done in Zope also looks butt-ugly, so something may indeed be needed. I think that at some...

    Python Success Stories Introduction This article shows how I integrated Python, COM, DocBook, OpenJade, and Word together to create a documentation tool for BEACON, a visual programming environment. This documentation tool was used for code reviews in the software development methodology at my company, and led to significant (>$1M) in cost savings. Before starting this project, I had no prior experience using SGML, XML, or other document markup languages. It was only when I was perilously ...
