Answer 1

def balance(loans):
    # Enter data like that: IDIDI Dale 5
    name_b, name, EMI = input().split()
    paid_EMI = (loans[name_b]['P']*loans[name_b]['N']*loans[name_b]['R']+
                loans[name_b]['P'])*int(EMI)/(loans[name_b]['N']*12)
    left_EMI = loans[name_b]['N']*12 - int(EMI)
    print(name_b, loans[name_b]['name'], int(paid_EMI), left_EMI)

def main():
    loans = {
        'IDIDI':{
            'name': 'Dale',
            'P': 10000,
            'N': 5,
            'R': 0.04
        },
        'MBI': {
            'name': 'Harry',
            'P': 2000,
            'N': 2,
            'R': 0.02
        }
    }
    balance(loans)
