lona (conda): Lona is a web application framework, designed to write responsive web apps  in full Python. Web is a solved problem in Python since ages, but  traditionally Python handles only the server side. If you want to have  client side interaction like click events or you want update content live,  you have to write an additional Javascript application. Lona handles the  server side and the client side, and provides a simple, pythonic API to  write self contained views. Lona comes with a Javascript based browser  library that speaks a specialized protocol with the backend. This protocol  specifies messages like "hey frontend, please show $HTML" and "hey  backend, someone clicked on node XY"
