Jython is an implementation of the high-level, dynamic, object-oriented language Python written in 100% Pure Java, and seamlessly integrated with the Java platform. It thus allows you to run Python on any Java platform.

There is a newer version: 2.7.4

# To fully test this module, we would need a copy of the stringprep tables.
# Since we don't have them, this test checks only a few codepoints.
