Twill doesn't show forms

Question

I'm trying to login in https://accounts.coursera.org/ using twill for python I tried this sheet of code

import twill 
b = get_browser()  
b.go("https://accounts.coursera.org/")  
b.showforms()

twill doesn't detect the form in the page and showforms methods doesn't show anything !! Is that an internal issue in twill package or I'm misssing something

Answer 1

import twill 
import webbrowser

b = twill.get_browser()  
b.go("https://accounts.coursera.org/")  
page = b.result.get_page()
tmp_page = "tmp.html"
with file(tmp_page, "w") as f:
    f.write(page)
webbrowser.open(tmp_page)

# b.showforms()

I get a page that says..

Please use a modern browser with JavaScript enabled to use Coursera.

So I suspect that twill doesn't include a javascript interpreter?
