Brython is impressive. It renders quite well a lot of Python features. Even things like yield from, sets, generator.send(), dict.fromkeys, multiple inheritance and 0b1100101. But there are several problems with brython: - it can't render some obscure Python features. It's very hard to do a complete Python implementation. E.g: metaclass will fail. - debugging is terrible. - 120ko gziped to pay upfront, just to write code. No virtual dom or routing. Interesting concept none of the less. In electron it can be interesting.
