Brython
▻https://brython.info
Brython is designed to replace Javascript as the scripting language for the Web. As such, it is a #Python 3 implementation (you can take it for a test drive through a web console), adapted to the #HTML5 environment, that is to say with an interface to the #DOM objects and events.
