When choosing seat, indicate the row and column for the location; when choosing the price, like computer find the first available price; mark the sold seats by changing the price to 0. When a user specifies a seat, make sure it is available. Use loop to determine whether continue to order or not. In each seating chart should be displayed for user. When user stops ordering, your program should output the number of tickets ordered, and amount ordered. PS- the program is being written in python language and our insturctor has told us to us elif

Solution

Here is the code for you:

#!/usr/bin/python
seatPrices = [[10, 10, 10, 10, 10, 10, 10, 10, 10, 10],
           [10, 10, 10, 10, 10, 10, 10, 10, 10, 10],

           [10, 10, 20, 20, 20, 20, 20, 20, 10, 10],
           [10, 10, 20, 20, 20, 20, 20, 20, 10, 10],
