Does Jython work with Python 3?

Jython roadmap is definitely outdated. However, on Frank Wierzbicki’s Weblog (one of Jython’s main developers) you can get an update, telling that Python 3 is definitely on the radar. Unfortunately, it is not yet clear when, as it is stated in a comment in that same blog from 2010: Jython will reach 2.6 and later a 3.

Those benchmarks indicate that the Jython compiler is far from optimal. The equivalent code rewritten in Java would be an order of magnitude faster. These benchmarks show Jython performing hundreds of times worse. spectral-norm: 0.12 secs for CPython and 4.96 secs for Jython.

What version of Python is Jython?

How do you use Jython in Python?

2.3 Running Jython

  1. Print “hello”.
  2. Define an empty class.
  3. Import a Python/Jython file containing a class definition. Create an instance of that class.
  4. Import a module from the standard Python/Jython library, for example, re or os. path. Use a method from that module.
  5. Import a Java class, for example, java. util. Vector.

Is Jython supported?

Yes. Jython is an implementation of the Python language in Java. We strive to ensure that Jython remains as compatible with CPython as possible. The latest Jython release (2.2) implements the same language as CPython 2.2 and many of the CPython standard library modules.

Is Jython slower than Python?

In general, Jython is respectably fast for long processes, but it takes a while to get started. If you want to use Jython, go ahead and use Jython. Python != CPython anymore.
