Python

Resolver spreadsheets can be extended by user-code written in the Python programming language. Python is a mature language that has been around since 1990, and is steadily growing in popularity. It originated as a scripting language for the Unix world, but is now used for a wide range of tasks including web-development, science, system-administration, desktop applications, games and more. Python is a cross-platform, Open Source, dynamically typed, object oriented and interpreted language.

The Python philosophy emphasises clean and readable code, whilst allowing the maximum developer flexibility and power. Because of this emphasis on clarity and readability, Python is very easy to learn.

IronPython

IronPython is an implementation of the Python programming language which runs on the .NET Framework. It was originally created by Jim Hugunin (who also created Jython, Python for the JVM), but is now developed by a Microsoft team. IronPython has native access to the .NET framework classes, as well as being able to use libraries written in pure Python. IronPython is licensed with the Microsoft Permissive License which allows commercial use and redistribution.

The .NET Framework

The .NET framework comprises of a runtime (called the CLR: The Common Langauge Runtime) and an extensive set of libraries built on top of it. The runtime includes a fast Just-In-Time compiler (JIT) and is optimised for multi-threading with multi-core processors. It provides built-in garbage collection and security features.

The framework classes include the core libraries (the BCL: Base Class Libraries) and libraries for just about every aspect of development. Further libraries have been added with the release of .NET 3 which is available for Windows XP and included in Vista.

Since starting with IronPython, Microsoft have built support into various aspects of the .NET framework.

• Mono

  A cross-platform implementation of the CLR. It not only runs IronPython, but includes FePy as part of the distribution.
