A small grocery store has one checkout. You have been asked to write a program to simulate the grocery store as it checks out customers. YOU ARE REQURED TO USE A QUEUE TO SOLVE THE PROBLEM. The queue program is
class Queue: def __init__(self): self.items = []
def isEmpty(self): return self.items == []
def enqueue(self, item): self.items.insert(0, item)
def dequeue(self): return self.items.pop()
def size(self): return len(self.items)
Here are some guidelines: 1. A customer gets to the checkout every 1 5 minutes 2. The checker can process one customer every 5 15 minutes (depends on how many groceries customer has) 3. The program should find the average wait time for customers and the number of customers left in the queue . 4. Use the random number generator to get values for when customers get to the checkout and how long the checker will take.5. You are not required to use classes, but it might make things easier
Note: Please use python language and class method
(use Python languge please ) IDLE (python 3.5)
