[Tutor] Auto login of website

[Tony Cappellini]

Would anyone happen to have a small python program (with or without gui) 
that can

log a user into a website, at regular intervals ?

The program would have to take the following as input (can be hard-coded, 
or on the cmd line)

1. the URL of a website (http)
2. the user ID
3. the user pasword
4. click (simulate a keypress or mouse click) on the button to log the user in

if the user could not be logged in, due to the website being overloaded, 
then it would do a retry at the next interval (where the interval can be
supplied by the user, preferably in seconds)

I've already checked the Python Cookbook, didn't find a match for the 
keywords I used
