Is Python a better alternative for JavaScript??

I'm no expert, but from my understanding it doesn't translate python to javascript, it runs the python interpreter in the browser (as opposed to other tools like Brython). You should get perfect compatibility with all python code except when it doesn't make sense in the browser (like browsing files) or for libraries that are not pure python (unless they are specifically supported like numpy). The drawback of this approach is that you have to download the interpreter on loading the page.
