Question

7. A supermarket wants to reward its best customer of each day, showing the customer’s name on a screen in the supermarket. For that purpose, the customer’s sales are stored in a list and the customer’s name is stored in a corresponding list. Implement a function:5 pts

DefnameofBestCustomer(Sales, Customers)

that returns the name of the customer with the largest sale.

Write a program that prompts the cashier to enter all sales and customers, adds them to two lists, calls the function that you implemented, and displays the result. Use a sales of 0 as a sentinel.

                        Loop

                                    Enter customer:

                                    Enter Sales:

                        Store these in 2 lists

                        Call function nameofBestCustomer

                        Print the name of the best customer

Python, keep it simple

Answer 1

Hey mate, the code for above program is provided below. Here I have used some built-in list methods (i.e. append(), max(), index() ) to make the program small and simple, make sure you have an idea about what these methods returns and what is their work.

If you are not familiar with them or want to recall them, then do check the method's information and syntax given below -

1. append(): Used for appending and adding elements to List. It is used to add elements to the last position of List.
Syntax:

list.append(element)

2. max(): Calculates and returns maximum of all the elements of List.
Syntax:

max(list)

3. index(): Returns the index of element present in the list. If there are more than one occurence of any element in the list then it returns the index of first occurrence.
Syntax:

list.index(element)

Do refer the screenshot of the code for proper indentation and error free execution.

PROGRAM -

sales=list()
customer=list()

def nameofBestCustomer(Sales,Customers):
    max_sales=Sales.index(max(Sales))
    return Customers[max_sales]
        
    
while True:
    c=input("\nEnter Customer: ")
    customer.append(c)
    s=int(input("Enter Sales: "))
    sales.append(s)
    
    if s==0:
        break

best_customer=nameofBestCustomer(sales,customer)
print("\n\nName of the best customer is: " + best_customer)
