Question

所以我想制作一个简单的循环程序但是我有一个问题：

def Lottery():
    Cash = 200
    YourNumber = randint(1, 10)
    while YourNumber != WinningNumber:
        Cash = Cash - 10
        if Cash < 0:
            print("You are out of money!")
            break
        YourNumber = randint(1, 10)
    else:
        Cash = Cash + 100
        Lottery()

问题是在def的最后一行，“cash”会在重新启动循环时自动重置为200。也许这有一个非常简单的解决方案，但我用Google搜索并尝试没有任何结果。

Answer 1

同样的事情（无限循环，但如果没钱，没有递归调用就会中断），

def Lottery():
    Cash = 200
    YourNumber = randint(1,10)
    while 1:
        if YourNumber != WinningNumber:
            Cash = Cash - 10
            if Cash <= 0:
                print("You are out of money!")
                break

            YourNumber = randint(1,10)
        else:
            Cash = Cash + 100

Answer 2

将Cash作为参数传递，设置默认值：

def Lottery(Cash = 200):
    YourNumber = randint(1,10)
    while YourNumber != WinningNumber:
        Cash = Cash - 10
        if Cash < 0:
            print("You are out of money!")
            break

        YourNumber = randint(1,10)
    else:
        Cash = Cash + 100
        Lottery(Cash)

代码提示：您可以使用+=和-=作为加/减和分配的快捷方式，以及其他一些更改：

def lottery(cash = 200):
    while randint(1, 10) != WinningNumber:
        cash -= 10

        if cash <= 0:
            print("You are out of money!")
            break
    else:
        lottery(cash + 100)
