The program operates until the clerk enters a zero for the zip code at the end of the day. At the end of the day. the program will display the following: A count of the number of items ordered by all customers. A count of the number of items ordered by customers under 30. A count of the number of items ordered by customers over 65. A total count of how many customers ordered items. You will turn in your: inputs outputs pseudocode flowchart desk check Python code.

Explanation / Answer

inputs: age, zipcode, items

outputs:

Number of items ordered by all customers
Number of customers below the age of 30
Number of customers over the age of 65
Total number of customers

python code:

class Customer:
    age = 0
    zipcode = 0
    items = 0
    def __init__(self, age, zipcode, items):
        self.age = age
        self.zipcode = zipcode
        self.items = items

customers = []
age = input('Enter customer age: ')
items = input('Enter the number of items ordered by customer: ')
zipcode = input('Enter the zipcode of the customer: ')
while zipcode != 0:
    customer = Customer(age, zipcode, items)
    customers.append(customer)
    age = input('Enter customer age: ')
    items = input('Enter the number of items ordered by customer: ')
    zipcode = input('Enter the zipcode of the customer: ')
under30 = 0
over65 = 0
num_items = 0
for customer in customers:
    if customer.age<30:
        under30 += 1
    if customer.age>65:
        over65 += 1
    num_items += customer.items
print "Number of items ordered by all customers: ", num_items
print "Number of customers below the age of 30: ", under30
print "Number of customers over the age of 65: ", over65
print "Total number of customers: ", len(customers)
