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.

If your client entered an action, assign it to the variable action. If they entered nothing, use the default action "Hold".
Assign the action to the variable do_action if trades can be done today, otherwise assign it as False.
Print the action that should be done.
