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.
Using urllib you can't perform a click on an <a> tag. You may want to look into selenium-webdriver for that matter.
You can fetch its href attribute value and then call the urllib.urlopen(path) function (make sure path variable contains the full path and not the relative path).
