如何計算信用卡的固定月付款

Question

如何繼續以下循環，直到找到mmp = 310 ？ 到目前為止，使用我的代碼，我能走的最遠是mmp = 240 。 您認為我還應該再有一個if陳述嗎？

balance = 4213
annualInterestRate = 0.2
mir = annualInterestRate/12
monthlyPaymentRate = 0.04


rb = balance
mmp = 0
Month = 1
while Month <= 12: 
    print('Month:' + str(Month))  
    mmp = mmp + 10
    print('Minimum monthly payment:' + str(mmp))
    ub = rb - mmp
    rb = round(ub + (annualInterestRate/12 * ub), 2)
    Month = Month + 1 
    print('Remaining balance:' + str(rb))
if rb > 0:
    rb = balance
    Month = 1
    while Month <= 12:
        print('Month:' + str(Month)) 
        mmp = mmp + 10
        print('Minimum monthly payment:' + str(mmp))
        ub = rb - mmp
        rb = round(ub + (annualInterestRate/12 * ub), 2)
        Month = Month + 1 
        print('Remaining balance:' + str(rb))

else:
    print('Lowest Payment:' + str(mmp)

如果您只是想達到該數字，則可以使用while mmp < 310:代替while Month <= 12: while mmp < 310: 或while rb > 0:如果要繼續循環直到所有費用都支付完畢。

如果需要循環數月（順便說一句， 如果您提到您的問題是家庭作業 ， 通常在這里受到贊賞 ），則可以添加數年的外部循環：

year = 1
while rb > 0:
    month = 1
    while month <= 12:
        # do stuff
        month = month + 1
    year = year + 1
