fill out a webform that uses javascript with pytho

Question

i am trying to fill out a webform using a python program by submitting specific values. the problem is it uses javascript. i will post an example of the value i want to fill.

fo.addVariable("email","[e-mail]")
fo.addVariable("age","19")
fo.addVariable("gender","M")
fo.addVariable("line","hello")

that is an example of the value on the page. what i want to do is submit a value to that and change it. what i am currently attempting is this:

data = urllib.parse.urlencode({"line": "hello", "age": "50", "email":  "[e-mail]", "gender": "M"}).encode()
resp = urlreq.urlopen("http://url.com/update", data) 

this usually works for most webforms. but for this one it will not.

Answer 1

In python 2.7, urllib has no attribute urllib.parse and a .encode() function at the end is unnecessary.

I think what you should be writing is

data = urllib.urlencode({"line": "hello", "age": "50", "email":  "[e-mail]", "gender": "M"})
