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.

Here is a Python program to calculate the discount and net payable amount based on the provided criteria using a user-defined function:

def calculate_discount(shopping_amount, is_member):
    """
    This function calculates the discount and the net payable amount.
    :param shopping_amount: Total shopping amount
    :param is_member: Boolean indicating if the customer is a store member
    :return: Net payable amount
    """
    discount = 0
    if shopping_amount >= 2000:
        discount = 0.10
    elif shopping_amount >= 1000:
        discount = 0.08
    elif shopping_amount >= 500:
        discount = 0.05

    if is_member:
        discount += 0.05

    discounted_amount = shopping_amount * discount
    net_payable_amount = shopping_amount - discounted_amount
    return net_payable_amount

# Example Usage
amount = float(input("Enter the shopping amount: "))
member_status = input("Is the customer a member (yes/no)? ").strip().lower()

if member_status == 'yes':
    is_member = True
else:
    is_member = False

net_amount = calculate_discount(amount, is_member)
print(f"Net Payable Amount: {net_amount:.2f}")
