python - 互联网服务提供商计划

Question

我正在编写一个互联网服务提供商程序。我的代码问题是它没有正确打印每月账单。

例如: 如果用户输入套餐“A”和使用的小时数(例如 9 小时) 那么当调用函数 printBill 时，它应该打印 9.95

我的问题:如何将 getPackage() 中的数据调用到函数 printBill()

#Bill for Package A
def getPackageA(hours):
    if (hours < 10):
        return 9.95 #Cost of Package A
    else:
        return (hours-10)*2 + 9.95

#Bill for Package B
def getPackageB(hours):
    if (hours < 20):
        return 13.95 #Cost of Package B
    else:
        return (hours - 20) + 13.95

#Bill for Package C
def getPackageC():
    return 19.95 #Cost of Package C

#Print Bill and savings
def printBill(bill):
    if (bill != 0):
        print("Your monthly bill is $", format(bill, '.2f'), 
        sep = '')
        getSavings(bill)
        print()
        print()
    else:
        print()


#Checks and display savings if applicable
def getSavings(bill):
    if(bill > getPackageA(hours)):
        print("If you had package A, you'd save $",\
            format(bill - getPackageA(hours),'.2f'), sep = 
            '')
    if(bill > getPackageB(hours)):
        print("If you had package B, you'd save $",\
            format(bill - getPackageB(hours),'.2f'), sep = 
            '')
    if(bill > getPackageC()):
        print("If you had package C, you'd save $",\
              format(bill - getPackageC(), '.2f'), sep = '')

def main():
    bill = 1
    #Asks user to enter choice of package and hours used
    packageChoice = str(input("Enter package purchased (A, 
    B, or C): "))
    hours = int(input("Enter the number of hours used: "))

    if(packageChoice == 'A' or packageChoice == 'a'):
        getPackageA(hours)
    elif (packageChoice == 'B' or packageChoice == 'b'):
        getPackageB(hours)
    elif (packageChoice == 'C' or packageChoice == 'c'):
        getPackageC()
    else:
        print("Package choice must be A, B, or C.")

    printBill(bill)

main()

Answer 1

您可以向函数传递多个参数。

def printBill(bill)

变成:

def printBill(bill,hours):

你可以这样调用它:

printBill(bill,hours)

您还必须以相同的方式将其传递给 getSavings。
