Implementation of the python version

[slopjong]

@eastein I know I'm a bit late with this ticket but as you're a python developer you might be interested to put your fingers on index.py, am I wrong?

When I started with the python version I had in mind to keep it as a single script. If you want to use flask or something like that, try to keep the directory structure as small as possible but. At least on the top-level.

The js/css/img should be shared so to make it easy to maintain/replace.

Yes, sure.
