Question

Energy consumption is measured in units of kilowatt hours (kWh). The more kWh a household use in a month, the higher the energy bill. A power company charges customers $0.12 per kWh for the first 500 kWh. After the first 500 kWh, the rate is $0.15 per kWh. Write a program to calculate energy charge. You must write and use the following two functions. (a) A main function: Ask the user to enter number of kWh used. Call the bill_calculator function and pass number of kWh used to it as an argument. (b) A bill_calculator function: This function has a parameter to receive number of kWh used. Calculate and display the energy charge.

Answer 1

Answer:

def bill_calculator(power):
    if power <= 500:
        return power * 0.12
    else:
        return (500 * 0.12) + ((power - 500) * 0.15)


def main():
    power = float(input('Enter kilowatt hours used: '))
    print('Please pay this amount: ' + str(bill_calculator(power)))

main()
