Python Coding Help

Create a program that calculates and prints the amount of change to be returned to the customer after paying the bill, based on the manager's input in the system.

Sample Input:

Total Invoice amount(In Dollars): 200

Amount of Tip (In cents): 10

Total Payment received by card: 160

Service Charged on payment made by card: 4%

Total Payment received in Cash(In Dollars): 100

Output:

Change to be returned to the customer (In Dollars): 53.50

Note: If the return to the customer is negative, then it must print 'outstanding amount and need to be paid by customer:', and the amount need to be paid

# Python solution:

def calculate_change(invoice_amount, tip_amount, card_payment, service_charge, cash_payment):
    # Convert service charge percentage to decimal
    service_charge_decimal = service_charge / 100
    
    # Calculate total payment made by card (including service charge)
    total_card_payment = card_payment * (1 + service_charge_decimal)
    
    # Calculate total payment (card + cash)
    total_payment = total_card_payment + cash_payment
    
    # Calculate the change to be returned
    change = total_payment - (invoice_amount + tip_amount)
    
    return change

# Get user input
invoice_amount = float(input("Total Invoice amount (In Dollars): "))
tip_amount = int(input("Amount of Tip (In cents): "))
card_payment = float(input("Total Payment received by card: "))
service_charge = float(input("Service Charged on payment made by card (%): "))
cash_payment = float(input("Total Payment received in Cash (In Dollars): "))

# Calculate and print the change
change = calculate_change(invoice_amount, tip_amount, card_payment, service_charge, cash_payment)

if change >= 0:
    print(f"Change to be returned to the customer (In Dollars): {change:.2f}")
else:
    print(f"Outstanding amount and need to be paid by customer: {-change:.2f}")

This program takes user inputs for the invoice amount, tip amount, card payment, service charge percentage, and cash payment. It then calculates the total payment, including the service charge, and determines the change to be returned. If the change is negative, it prints the outstanding amount that needs to be paid by the customer
