我不断得到一个语法错误，不知何故是由于函数定义末尾的冒号

Question

我对python和编程都是全新的，所以这可能是非常简单的事情，但在定义minPayment函数的最后一行中，我一直遇到这个语法错误。我看不出有什么问题。。。这是到目前为止的节目

习题1：信用卡余额计算器

print 'Month 1'
OutstandingBalance = raw_input(float('enter your balance'))
AnnualInterestRate = raw_input(float('enter rate as a decimal(%/100)'))
MinimumMonthlyPaymentRate = raw_input(float('enter minimum monthly payment rate as a decimal(%/100)'))
def minPayment: 
     minPayment = MinimumMonthlyPaymentRate * OutstandingBalance
        print 'minimum payment='minPayment
    return minPayment
def accIntrst:
    accIntrst = (AnnualInterestRate/12.0) * OutstandingBalance
        print 'accrued interest = 'accIntrst
    return accIntrst
def balPaid:
    balPaid = accIntrst - minPayment
        print 'balance paid = 'balPaid
    return balPaid
def remBal:
    remBal = OutstandingBalance - balPaid
        print 'remaining balance = 'remBal
    return remBal

非常感谢您的反馈

Answer 1

在函数中添加括号。Python语法规定了这一点

因此，与其写def minPayment:，不如写def minPayment():
