I'm writing a python script to grab my bank account details using urllib. 
To access the login page, there is a hyperlink button present on the page. How can I get my script to click that button or indeed bypass it?
Please, any help me on this would be appreciated.
I want to add to Jason's answer that if you're going to pass login data you might want to step away from urllib and use requests.
I would find the url of the page that has the login form and use requests there.
