Question

我似乎在麻省理工学院6.00SC课程中坚持这个问题。我是编程新手。

问题：问题1 如果一个人只支付一个人，那么写一个程序来计算一年后的信用卡余额每月信用卡公司要求的最低月付款。使用raw_input（）来请求以下三个浮点数：

信用卡上的未结余额
年利率
最低月付款率

每个月打印最低月付款，余额，支付原则格式如下面的测试用例所示。所有数字应四舍五入到最近的便士。最后，打印结果，其中应包括当年支付的总金额和剩余金额平衡。

这是我的新代码：

outstand_balance = float(raw_input('Enter the outstanding balance on your credit card:'))
ann_interest_rt = float(raw_input('Enter the annual credit card interest rate as a decimal:'))
min_month_rt = float(raw_input('Enter the minimum monthly payment as a decimal:'))
Month = int(1)
for month in range (0,12):
    Min_monthly_payment = round((min_month_rt * outstand_balance), 2)
    Interest_paid = round((ann_interest_rt/12 * outstand_balance), 2)
    Principle_paid = round((Min_monthly_payment - Interest_paid), 2)
    outstand_balance = round((outstand_balance - Min_monthly_payment), 2)
    Remaining_balance = round((outstand_balance - Min_monthly_payment) * (1 \+(ann_interest_rt/12)), 2)
    Month +=1
    print "Minmimum monthly payment $" + str(Min_monthly_payment)
    print "Principle Paid $" + str(Principle_paid)
    print "Remaining Balance $" + str(Remaining_balance)
    print "Month: " + str(Month)

结果如下：

    Enter the outstanding balance on your credit card:4800
Enter the annual credit card interest rate as a decimal:.2
Enter the minimum monthly payment as a decimal:.02
Minmimum monthly payment $96.0
Principle Paid $16.0
Remaining Balance $4684.8
Month: 2
Minmimum monthly payment $94.08
Principle Paid $15.68
Remaining Balance $4591.1
