Question

must be in python

Part 1 - the Item class – An Item object will represent one grocery item.

Define a class named Item that has the following attributes:

name – the name of the grocery item

price – the price of the item

quantity – the number of items that are needed

The Item class should have an __init__ method for creating an Item object.   The __init__ method should accept parameters which provide initial values for the object:

   __init__(self, newname, newprice, newquantity)

The Item class should provide a method ‘increaseCount’ which increases the quantity stored in the object by 1.

   increaseCount(self)

Finally, the Item class should provide a method named ‘printAll’, which prints the name, price and quantity stored in the object

    printAll(self)

Part 2 – Class Tester

Write a simple main that demonstrates that your Item class works. That means that it is possible to use this class to create an Item object, increase the count stored in that object and output the data contained in that object.

Answer 1

class Item:
    def __init__(self, newname, newprice, newquantity):
        self.name = newname
        self.price = newprice
        self.quantity = newquantity

    def increaseCount(self):
        self.quantity += 1

    def printAll(self):
        print("Name:",self.name,", Price:",self.price,", Quantity:",self.quantity)

# Tester
def main():
    i = Item("apple",35,5)
    i.printAll()
    i.increaseCount()
    i.printAll()

main()

Name: apple , Price: 35 , Quantity: 5
Name: apple , Price: 35 , Quantity: 6
