You can also use Js2Py which is written in pure python and is able to both execute and translate javascript to python. Supports virtually whole JavaScript even labels, getters, setters and other rarely used features.

import js2py

js = """
function escramble_758(){
var a,b,c
a='+1 '
b='84-'
a+='425-'
b+='7450'
c='9'
document.write(a+c+b)
}
escramble_758()
""".replace("document.write", "return ")

result = js2py.eval_js(js)  # executing JavaScript and converting the result to python string

Advantages of Js2Py include portability and extremely easy integration with python (since basically JavaScript is being translated to python).

To install:

pip install js2py

Using PyV8, I can do this. However, I have to replace document.write with return because there's no DOM and therefore no document.

import PyV8
ctx = PyV8.JSContext()
ctx.enter()

js = """
function escramble_758(){
var a,b,c
a='+1 '
b='84-'
a+='425-'
b+='7450'
c='9'
document.write(a+c+b)
}
escramble_758()
"""

print ctx.eval(js.replace("document.write", "return "))

Or you could create a mock document object

class MockDocument(object):

    def __init__(self):
        self.value = ''

    def write(self, *args):
        self.value += ''.join(str(i) for i in args)


class Global(PyV8.JSClass):
    def __init__(self):
        self.document = MockDocument()

scope = Global()
ctx = PyV8.JSContext(scope)
ctx.enter()
ctx.eval(js)
print scope.document.value

Should I switch from JavaScript to python

I’d recommend not learning Python and sticking with HTML/CSS/JavaScript - why? The web is king, if you want to share what you build, you use the web. JavaScript is the only programming language you can use for the frontend. Yes there is more to learn, but it is so rewarding once the pieces start falling together. You can get so much done with just the basics of CSS once you understand Flexbox and/or Grid. HTML is so easy you can learn it in a few hours. What do you want to build? I’d only bother with Python if I was exploring Machine Learning, Statistics, data structures and algorithms, or I wanted to create APIs with Flask/FastAPI. Python is crap for gaming, GUIs, and definitely not first choice for a backend language. Python is a great second language to know, it is a great support language and data language, it’s a great beginner language, but it’s not the best language for almost anything except data. If you just want to build local things for yourself sure it’s a good choice and easy to get started. I say all this as someone who started my programming journey with Python as my first language for about 2 years, before branching out. Really think about what you want to build and choose a language based off that, rather than choosing what’s “easy” More on reddit.com

How do I integrate python code with javascript to make a website?

What you are looking for is building a frontend (website with javascript/react) that interacts with your backend (python code) through the use of (presumably REST) APIs In other words a web fullstack project. More on reddit.com

Anyone who has worked with both Python and Javascript for backend work, which one do you prefer and why?

I prefer Django as framework more than python as a language. It has well established ecosystem and comes in with loads of support for a lot of std features in web dev + a really good internal dashboard More on reddit.com
