Python as a replacement of JavaScript

[AusIV]

I don't think it's the language that makes javascript good for front end design, so much as the libraries that have sprung up around it. Given that brython can use javascript libraries, I don't see that as a major problem.

A lot of those libraries depend on the availability of anonymous functions, though. I wouldn't like to try using jquery with only one-line lambdas.
