Python Language Jython


Example

Open-source implementation for JVM written in Java, licensed under Python Software Foundation License. It supports only version 2.7, version 3 is currently being developped.

Differences with CPython:

  • Tight integration with JVM.
  • Strings are Unicode.
  • Does not support extensions for CPython written in C.
  • Does not suffer from Global Interpreter Lock.
  • Performance is usually lower, though it depends on tests.

Hello World

print "Hello World!"

You can also use Java functions:

from java.lang import System
System.out.println("Hello World!")
