How to 'login' to secure website using python for a webpage that uses java and does not have any real source when viewing page source

I would like to make a script to login into my bank and download the latest transactions but I am stumped at the login page as it seems to be dynamically created each time and very little helpful information in the page source. I am new to using Python for this task and would appreciate any direction on how to do this. I get that most websites login would use some form of post to send the username and password but my bank has done something crazy to be secure which I guess is fine but it is not helping my cause....

This is the login page I would like to login into using Python.
