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 (qu.py) is located on the Instructor drive.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
