3. 모듈 - 수입과 공과금

    result = waterPrice + elecPrice + gasPrice
    return result

    result = getUtilityBill() / getIncome() * 100
    return result

import utilityBill as ut
intputIncome = int(input('수입:'))
w = int(input('수도세:'))
e = int(input('전기세:'))
g = int(input('가스요금:'))

ut.setIncome(intputIncome)
ut.setWaterPrice(w)
ut.setElecPrice(e)
ut.setGasPrice(g)

print(f'총 공과금 비용: {ut.getUtilityBill()}')
print(f'수입 대비 공과금 비율: {int(ut.getUtilityRate())}%')
