Jep - Java Embedded Python
Jep embeds CPython in Java through JNI.
Some benefits of embedding CPython in a JVM:
Using the native Python interpreter may be much faster than alternatives.
Python is mature, well supported, and well documented.
Access to high quality Python modules, both native CPython extensions and Python-based.
Compilers and assorted Python tools are as mature as the language.
Python is an interpreted language, enabling scripting of established Java code without requiring recompilation.
Both Java and Python are cross platform, enabling deployment to different operating systems.
Installation
Simply run pip install jep or download the source and run
pip install .. Building and installing require the JDK and Python,
to be installed beforehand. Pip will need to be able to install setuptools
and numpy to build jep.

- NumPy >= 1.7 (optional)
Notable features
- Interactive Jep console much like Python's interactive console
