1. Python seamlessly integrated with Java 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 complementary to Java and allows the two languages to be freely mixed. It is especially suited for embedded scripting, interactive experimentation and rapid application development, and it can interact with Java packages or with running Java applications.
