Best way to integrate Python and JavaScript?

This question is not exactly young, but there have come up some alternatives:

• "Skulpt is an entirely in-browser implementation of Python."
• Brython - "A Python 3 implementation for client-side web programming"
• RapydScript - "Python-like JavaScript without the extra overhead or quirks"
• Transcrypt - "Lean and mean Python 3.6 to JavaScript compiler with multiple inheritance, sourcemaps, static type checking and selective operator overloading." (also on Github)

there are two projects that allow an "obvious" transition between python objects and javascript objects, with "obvious" translations from int or float to Number and str or unicode to String: PyV8 and, as one writer has already mentioned: python-spidermonkey.

there are actually two implementations of pyv8 - the original experiment was by sebastien louisel, and the second one (in active development) is by flier liu.

my interest in these projects has been to link them to pyjamas, a python-to-javascript compiler, to create a JIT python accelerator.

so there is plenty out there - it just depends what you want to do.

How about pyjs?

From the above website:

pyjs is a Rich Internet Application (RIA) Development Platform for both Web and Desktop. With pyjs you can write your JavaScript-powered web applications entirely in Python.

Here's something, a Python wrapper around the SeaMonkey Javascript interpreter... http://pypi.python.org/pypi/python-spidermonkey
