Question

You are contributing to a system that will help an ice cream shop to keep track of their product line and calculate the price of customer orders.

In a Python file called icecream.py, write a class called IceCream that matches the following docstring:

Part A:

'''
Class -- IceCream
Represents a type of ice cream.
Attributes:
flavor -- The name of the flavor, a string e.g. "chocolate" or "cookies and cream"
price_per_scoop -- The price per scoop, a float.
Method:
...See part B...
'''

Part B 

Add a method called get_cost to the IceCream class that will be used to calculate the cost of a customer's order. The method should take a float parameter, the number of scoops the customer wants, and return the total cost for that amount of ice cream. Here are the rules for calculating the ice cream cost:

  • The cost of the ice cream is the number of scoops multiplied by the price per scoop.
  • For less than 2 scoops, the cost is calculated as the price per scoop multiplied by 2. This means that an order for less than 2 scoops of ice cream costs the same as 2 scoops.
  • For large orders, defined as more than 10 scoops, the company takes $2 off the cost.

Write a test file to test the class you wrote for icecream.py . Be sure to test the constructor as well as the method you wrote in part B.
