Check Your Clipper Card (San Francisco Transportation)
Like the Starbucks Pythonista script I made, this too transfers your password in plain text and probably should not be used. Granted, it does perform a useful task to me. It uses the Check Clip API from http://checkclip.herokuapp.com to grab the balance of your Clipper Card (a magic card people in San Francisco wave over sensors to ride on most forms of public transit).
You can store your log in and clipper card data in variables at the top of the code so you do not have to remember all this log in information. (You can choose to store just one of the variables if you prefer.) By storing variables you can also have it check a second card, that you are not prompted to do otherwise.
