[Tutor] Vending machine program
H I wanted to create a program called vending machine and I wondered if you could do it so I can find out how to do it. Here is how it should work like: A food vending machine accepts 10p, 20p, 50p and £1 coins. One or more coins are inserted and the current credit is calculated and displayed. A product is selected from those available. The system checks to see if there is enough credit to purchase the product chosen. If there is not enough credit the system displays an error message. If there is enough credit it dispenses the product, updates the credit available and displays the remaining credit. Further selections can be made if there is enough credit. The vending machine simulation should have five products and prices. Design, code, test and evaluate a program for this simulation.

No. This list is meant to help people with specific questions about their python programs. If you make an attempt at writing this program and get stuck or have questions on how to proceed, we will be happy to give you hints and help you out. But we won't do your work for you.

What prior programming experience do you have? As already mentioned we prefer to not do your work for you. Further selections can be made if there is enough credit. This is confusing. You could drop that line with no ill effect. I am not sure what it even means. How far did you get in the steps suggested? Did you attempt a design? -- Bob Gailer 919-636-4239 Chapel Hill NC ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Thank you ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor I would suggest a general design with VendingMachine class with these properties: - product list (if you don't need to handle running out of products) - credit (int, in pence) - method to list products and credit - method to add to credit - method to buy a product A separate class that handles user interface: main loop, accepting the commands: add amount, select product; a method that runs continuously until a valid command is provided then the command is returned. In the main loop, products are listed, user provides the command, command is delegated to one of VendingMachine methods and then loop goes back to the beginning.
