The twill python module with Fedora 25.

Today I tested the twill python module with python 2.7 and Fedora 25.
This is: a scripting system for automating Web browsing. Useful for testing Web pages or grabbing data from password-protected sites automatically.
To install this python module I used pip command:
[root@localhost mythcat]# pip install twill
Collecting twill

[mythcat@localhost ~]$ python

>>> from twill import get_browser
>>> b = get_browser()
>>> 
>>> from twill.commands import *
>>> go("http://www.python.org/")

To talk to the Web browser directly, call the get_browser function.
You can see most of the twill commands by using:
>>> import twill.shell
>>> twill.shell.main()
