Jython is an implementation of the high-level, dynamic, object-oriented
language Python seamlessly integrated with the Java platform. The
predecessor to Jython, JPython, is certified as 100% Pure Java. Jython is
freely available for both commercial and non-commercial use and is
distributed with source code. Jython is complementary to Java and is
especially suited for the following tasks: Embedded scripting - Java
programmers can add the Jython libraries to their system to allow end
users to write simple or complicated scripts that add functionality to the
application. Interactive experimentation - Jython provides an interactive
interpreter that can be used to interact with Java packages or with
running Java applications. This allows programmers to experiment and debug
any Java system using Jython. Rapid application development - Python
programs are typically 2-10X shorter than the equivalent Java program.
This translates directly to increased programmer productivity. The
seamless interaction between Python and Java allows developers to freely
mix the two languages both during development and in shipping products.
