Python in the browser

#python #web

You can use Python on the web, instead of Javascript.
Yes, really.

There's a project named Brython: "A Python 3 implementation for client-side web programming".

So how does it work:

Step 1: Include Brython

<script type="text/javascript" src="/src/brython.js"></script>

Step 2: Write your code, say

<body onload="brython(1)">

<script type="text/python">
from browser import document, alert

def echo(ev):
    alert("Hello {} !".format(document["zone"].value))

document["test"].bind("click", echo)
</script>
<p>Your name is : <input id="zone" autocomplete="off">
<button id="test">clic !</button>
</body>

Has this any benefit? I mean, it seems like this adds a new complexity layer to any project without any benefit, everything which is a wrapper or non native become slower and non maintainable in a long term.
Up to now this just push a personal preference without even consider the disadvantages of the tech debt it will generate.

JS is a magic language for browser/DOM/frontend stuff... it's useless to use another language (made with other kind of stuff in mind).

But, hey, It looks cool anyway.

In theory that's very cool, but I tested it for an extension project where I needed python,
that was very painful to use for the moment, because brython doesn't support some functions related to DOM, etc.
So I hope this will get better and better.
Cool module tho. :)
