Is there a relatively quick program out there to accomplish at least the basics of this? Just a few regexes? I'm willing to do some manual conversion, but this is a pretty big set of scripts. More on stackoverflow.com

March 18, 2025I just gave ChatGPT 200+ lines of JavaScript code and asked it to translate the code into Python. The code parses text using regular expressions. It was complex. 2 minutes later and I had Python code that worked flawlessly. This thing just saved me a couple of days of work.

This will convert the input string with all the extensions enabled (comparable to adding the '-5' option) and so it will take some time because of BabelJS load times. This offers many ways to test the framework, both the string conversion and the evaluation using the embedded JavaScript interpreter are very handy. For example: $ pj -s '"foo" if True else "bar"' (true ? "foo" : "bar"); ... You can use metapensiero.pj in python code as well.

You can translate JavaScript to Python using Js2Py. It supports whole JavaScript and you can use it to translate large JavaScript modules like esprima.js (a JavaScript 6 parser).
Short demo:
>>> import js2py
>>> f = js2py.eval_js( "function $(a) {return a + arguments[1]}" )
>>> f
function $(a) { [python code] }
>>> f(1, 2, 3)
3
This is how the translated function looks like internally (it's rather ugly):
>>> print js2py.translate_js( "function $(a) {return a + arguments[1]}" )
from js2py.pyjs import *
var = Scope( JS_BUILTINS )
set_global_object(var)
# Code follows:
var.registers([u'$'])
@Js
def PyJsHoistedNonPyName(a, this, arguments, var=var):
var = Scope({u'a':a, u'this':this, u'arguments':arguments}, var)
var.registers([u'a'])
return (var.get(u'a')+var.get(u'arguments').get(u'1'))
PyJsHoistedNonPyName.func_name = u'$'
var.put(u'$', PyJsHoistedNonPyName)

Now several (4) years later this (almost certainly) can be done; though certainly not with RegEx. I suggest future readers look to @Piotr Dabkowski's answer.. Or some of the other answers. (I don't know having not tried them)
Original Answer
Hm this is a hard one. The definition of a compiler is translates from a higher level language to a lower level language. eg python to machine-code. or java to javascript (google has a rather famous compiler for this somewhere - its' what makes google doc easier to make) Python to javascript compilers abound. technically javascript to python would be a decompiler. (afaik)
I found some speculation about a javascript-python converter here: follow the tread through. it mostly speaks of how it wouldn't be too hard to do. I can't find anything , but that doesn't mean it's no out there.
Regex is not suitable, regex is suitable only for regular languages. programming languages are not normally regular languages. see this

r/Python on Reddit: Converting Python to Javascript
January 30, 2018 -
Hello!
New to Python and programming in general. I created a program that I would hope to run on a website. However, our platforms at work are JS or PHP. Is there a way to convert Python script into JS? Basically, a Google translate for scripting languages.
Thanks!

PHP is a backend language that generates html pages. Javascript is a frontend language (can also be used as backend with node) that runs in your browser. So the question is really do you want to convert something on the frontend or the backend. If backend you can just use python as is with something like flask or django. If it is frontend then python wasn't made to run in the browser. However there are things like https://www.transcrypt.org/ https://brython.info/static_doc/en/intro.html?lang=en
