You will need to create a new dictionary where the keys are the vending machine labels, and the values are a new type of object called a MachineStatus'. For each instance, the MachineStatus class should store: the label of a vending machine the total amount of beverages the vending machine was previously stocked with the total amount of beverages currently in stock in the vending machine the total income of the machine from the last time it was stocked until now (note: beverages have different prices, so you cannot simply multiply the change in stock times $1.50 to get the total income) Three major modifciations to 'vending status_checker.py are necessary: adding the MachineStatus class adding to the loop for counting beverages additional code for counting and updating a vending machine's MachineStatus object values enabling a user to choose the machines' sales report, not just the inventory report, and then display the report as shown in the following example Would you like the (m)achine report or the (i)nventory report? m Label REID_1F REID2F REID 3F Pct Sold Sales Total 52.40%$ 230.25 42.02% $ 138.25 52.07% $ 214.75 You will need to create a new dictionary where the keys are the vending machine labels, and the values are a new type of object called a MachineStatus'.
