Assigning variables with Boolean operators

You can use the fact that and and or are short-circuit operators to assign objects to variables in intelligent ways. Pretend that you are deciding what actions you should take with a client's account based on what they entered in a web-form. Unfortunately, they could submit the form with this field empty, so you need to set a default action just in case. The supplied variable input_action has the contents submitted by the client. The supplied variable is_trading_day is True if today is a day that trades are possible.
