2. XYZ store plans to give festival discount to its customers. The store management has decided to give discount on the following criteria:
Shopping Amount Discount Offered
>=500 and <1000 5%
>=1000 and <2000 8%
>=2000 10%
An additional discount of 5% is given to customers who are the members of the store. Create a program using user defined function that
accepts the shopping amount as a parameter and calculates discount and net amount payable on the basis of the following conditions:
Net Payable Amount = Total Shopping Amount – Discount.
Ans.
def calculateDiscount(shoppingAmount, isMember):

# Define discount percentages based on shopping amount
if shoppingAmount >= 500 and shoppingAmount < 1000:
discountPercentage = 5
elif shoppingAmount >= 1000 and shoppingAmount < 2000:
discountPercentage = 8
elif shoppingAmount >= 2000:
discountPercentage = 10
