Question

我在使用python时遇到麻烦，因为它会不断返回此错误代码

 total_amount = loanpayment * years * 12
TypeError: unsupported operand type(s) for *: 'function' and 'int'

def loanpayment(principal, percentage, years):
    i = (percentage/100)/12
    n = years * 12
    P = principal
    loanpayment = (i*principal*((1+i)**n))/(((1+i)**n)-1)
    return loanpayment

principal = int(input(""))
percentage = float(input(""))
years = int(input(""))
num_payments = years * 12

total_amount = loanpayment * years * 12

print("Monthly payment : {}".format(loanpayment(principal,percentage,years)))
print("Total interest paid", interest, ".")

Answer 1

loanpayment是一个函数。

您需要使用参数进行调用。

在您的情况下：

loanpayment(principal, percentage, years)

完整行：

total_amount =  loanpayment(principal, percentage, years) * years * 12

python *：'int'和'function不支持的操作数类型
