Summary

Jython is an implementation of the Python programming language written in Java, allowing Python programs to integrate seamlessly with any Java code. The secret to Jython's popularity lies in the combination of Java's libraries and tools with Python's rapid development capabilities. Jython Essentials provides a solid introduction to the language, numerous examples of Jython/Java interaction, and valuable reference material on modules and libraries of use to Jython programmers.

Author Biography

Samuele Pedroni is one of the main Jython developers. He holds a CS flavored diploma in mathematics from the ETH Zurich (Swiss institute of technology in Zurich). He is now a teacher and research assistant at the Institute of Theoretical CS. He plans to come to the US for a PhD in the field of dynamic languages and dynamic compilation. He came to Jython with the interest in improving it with respect to Java importing and reloading. He has developed several important patches related to java integration, classloaders, and the reworking of java/python importing rules and design.

Noel Rappin has a Ph.D. in computer science from the Georgia Institute of Technology, where his research included methods for teaching Object-Oriented Programming and Design. He has extensive production experience in both Java and Python. Noel also contributed an introductory chapter to the book Squeak: Open Personal Computing and Multimedia (PH).
