Write the Python for this Main Menu

The main menu will ask the user to enter one of the following options:

New Customer

Order Pizza

Display Orders

Finalise Orders

Exit

How may I help you:

While the user has not entered take keyboard input for the user\'s choice. If the user enters invalid input, output

\"Please only enter choices The choices should do the following:

Call the method to set the customer name.

Call the method to select a Pizza from the pizza menu. If the user enters an invalid pizza name, output We do

not make that kind of pizza\" and return to the main menu. If the user successfully chooses a Pizza, output the

Pizza Submenu. If the customer name has not been entered, raise an Exception with the error message Must

enter customer name before ordering

Display the Order so far.

Save the Orders receipt. Then create a new empty Order.

If the user enters output \"Have a good day : and end the program.

Pizza Submenu

The Pizza Submenu will ask the user to enter one of the following options:

Change Size

Change Pizza Base

Add Topping

Remove Topping

Order

Cancel

What would you like to do:

While the user has not entered or take keyboard input for the users choice. Call the PizzaShop method that is

appropriate to the user\'s choice. If the user has not entered a valid choice, output \"Please only enter choices If

the user enters add the Pizza to the Order and return to the main menu. If the user enters return to the main

menu without adding the Pizza.
