贷款计算器
M = 0
L = raw_input("What is the loan amount you took? ")
i = raw_input("What is the interest for the loan amount? ")
k = raw_input("No of payments or years you are considering for this loan? ")
M = L[i(1+i)k] / [(1+i)k-1]
print("Your monthly payment is %f" %M)
错误:
M = L[i(1+i)k] / [(1+i)k-1]

无论您的输入是字符串还是数字,对于python中的乘法,您都必须在值之间指定*
。
如果您希望输入仅为数字或将input()
转换为int为raw_input()
int(raw_input())
您未在
处收到错误的原因L[i(1+i)k] / [(1+i)k-1]
^
是因为python认为i(1+i)
是一个函数调用。

我认为它应该是这样的。虽然如果你希望k减少然后乘以,我感到很困惑:
M = (L * (i * (1+i) * k)) / ((i+1) * (k-1))
或要递减的分母:
M = (L * (i * (1+i) * k)) / ((i+1) * k) -1)
此外,您不需要声明M = 0,因为它没有用处。
