This translates directly to increased programmer productivity. Rapid application development - Python programs are typically 2-10x shorter than the equivalent Java program.This allows programmers to experiment and debug any Java system using Jython. Interactive experimentation - Jython provides an interactive interpreter that can be used to interact with Java packages or with running Java applications.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.Jython is complementary to Java and is especially suited for the following tasks: Jython is freely available for both commercial and non-commercial use and is distributed with source code under the PSF License v2. Jython is a Java implementation of Python that combines expressive power with clarity.
