贷款计算器程序
问题描述:
到目前为止,我一直在编码这一整个星期试图让它工作。贷款计算器程序
应该站出来,因为这:
Please enter Amount that you would like to borrow(£): 4000
Please enter Duration of the loan(Years):2
Please enter the interest rate (%):6
The total amount of interest for 2 (years) is: £480.00
The total amount of the period for 2 (years) is £4480.00
You will pay £186.67 per month for 24 months.
Do you wish to calculate a new loan payment(Y or N)
代码:
monthlypayment = 0 #Variable
loanamount = 0 #Variable
interestrate = 0 #Variable
numberofpayments = 0 #Variable
loandurationinyears = 0 #Variable
loanamount = input("Please enter the amount that you would like to borrow(£) ")
loandurationinyears = input("How many years will it take you to pay off the loan? ")
interestrate = input("What is the interest rate on the loan? ")
#Convert the strings into floating numbers
loandurationinyears = float(loandurationinyears)
loanamount = float(loanamount)
interestrate = float(interestrate)
#Since payments are once per month, number of payments is number of years for the loan
numberofpayments = loandurationinyears*12
#calculate the monthly payment based on the formula
monthlypayment = (loanamount * interestrate * (1+ interestrate)
* numberofpayments/((1 + interestrate) * numberofpayments -1))
#Result to the program
print("Your monthly payment will be " + str(monthlypayment))
答
我看来像你在上面,从你描述的代码所缺少的仅仅是一个while循环。这将允许您的程序计算贷款并一遍又一遍地运行程序,直到用户输入no,在这种情况下程序退出。所有您需要做的是:
YorNo = input("Do you wish to calculate a loan payment")
YorNo.Title()
while YorNo != "n":
#Your code goes here
YorNo = input("Do you wish to calculate a loan payment")
YorNo.Title()
print("Thank you for using the program")
如果你不明白这一点,baisically,你只是你的代码之前输入第3行。然后你留下一个缩进,并在他们后面输入你的代码。一旦完成,您可以输入第3行和第4行。然后,只需回头是缩进(显示一个程序,这个心不是循环的一部分。)如果我不是错了,这样做的结果将是:
- 你会被要求无论您要计算贷款
- 如果你回答“y”,你的代码将运行,贷款将被计算并打印给用户
- 然后你会再次被问到。以上将重复,直到您输入“n” N不能被大写

那么会出现什么样的错误?此外,你应该可能将你的利率输入除以100. – ryugie
它基本上会是一个模糊的数量,如生病6,2,6,它会拿出类似6056235.14291821421542 –
欢迎来到堆栈溢出!我编辑你的问题来修复语法并使其更易读。另外,我更正了想要的输出中的推测错字('&' - >'£')。请[编辑]您的问题以包含完整的实际输出或发布的代码,以便我们有[mcve]。 –
