Best module for creating a web based form?

[snippsat]

Not knowing much about web development, but there seem to be great ways to run Python in the browser. What do you think of this?

I have done some testing with Brython a while ago,but did not use more than some test.
The problem with most of these approaches is that it's just a abstraction layer to avoid write some JavaScript code.

Usually is not much JavaScript that need to written if it's a small/medium size project as TS is doing in this Thread,
also Jinja(build into Flask) make is easy to transport Python code from server into HTML.

If look what used most on GitHub --> GitHut 2.0,so do we see that JavaScript and Python is clear ahead.
So it can be smart to learn some JavaScript if doing web-development,is not like that Modern JavaScript is so far away from Python anyhow.
