The Benefits of Python's Type System The PyDrone architecture could have been implemented in many languages, but Python's dynamic typing made it much easier to build our Property manager.

    ...building the GUI accordingly. This code is also used in MayaVi's persistence mechanism, which can save most VTK objects to disk by inspecting them at runtime. The use of introspection to write data-driven modules such as these avoided substantial amounts of manual coding, and makes MayaVi self-extending as additional VTK objects are defined. 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 bu...

The scientist doesn't have to learn a low-level programming language, and the C/C++ programmer doesn't need to understand the science involved. Without Python, large amounts of C/C++ code often have to be written just to provide a flexible enough input mechanism so that scientists can feed t...

This performance gain is a result of the fact that the XIST preprocessor takes care of many compute-intensive operations, that might require dynamic type introspection, string processing etc. and would be executed by the Java tag library code during page load.
