I am happy to announce the first release candidate of Jython 2.0.
Jython is a Java implementation of the Python programming language. It
allows users to compile Python source code to Java byte codes, and run
the resulting bytecodes on any Java Virtual Machine. It is a very
seamless and smooth integration with Java: from Python you have complete
access to all Java libraries, can build applets, can integrate with Java
beans, and can subclass Java classes in Python and vice versa. Like
Python, and unlike Java, Jython can also be used interactively: just
type some Jython code at the prompt and see the results immediately.
A java installer is available for download at the Jython website:
http://jython.sourceforge.net/
Installation is started by running the installer class. Further
information and tips on installation is available at:
http://jython.sourceforge.net/install.html
Jython 2.0 is feature compatible with Python 2.0 and among the
new features are:
- Augmented assignment, e.g. x += 1
- List comprehensions, e.g. [x**2 for x in range(10)]
- Extended import statement, e.g. import Module as Name
- Extended print statement, e.g. print >> file, "Hello"
The changes from beta 2 include:
New features
- Experimental support for reloading java packages. Thanks to
Samuele Pedroni for all his work on the Jython/Java integration.
Bug fixes.
- Prevent a NPE when a .jar on the classpath is corrupt. Instead
a message with the original IOException is printed.
A complete list of changes and differences are available here:

Bugs can be reported to the bug manager on SourceForge:

Cheers,
the jython-developers
