Jython is an implementation of the Python programming language written in Java that runs on the JVM, currently supporting Python 2.7 with work toward Python 3. It provides seamless interoperability between Python and Java code, allowing Python scripts to use Java classes and Java applications to embed a Python interpreter.

Use cases

• run python scripts on the jvm
• embed a python interpreter in a java application for user scripting
• call java classes and libraries from python code
• compile python code to java bytecode
• interactively explore and debug java packages from a python console
• use python for rapid application development alongside java
• access jdbc databases from python via zxjdbc

When to choose

• you need to mix Python and Java in the same application
• you want to offer end users a scripting extension language inside a Java product
• you must run legacy Python 2.7 code on the JVM
• you need JVM benefits like Java library access and threading for Python code

When to avoid

• you need Python 3 support, which is not yet released
• your project depends on C extension packages like numpy, which Jython cannot run
• you are starting a new Python project - use CPython and port to Python 3 instead
• you need the latest CPython standard library behavior
