python - Python：简单循环程序

Question

所以我想做一个简单的循环程序，但我有一个问题：

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 的最后一行中，“cash”会在重新启动循环时再次自动重置为 200。也许有一个非常简单的解决方案，但我已经用谷歌搜索并尝试过没有任何结果。

Answer 1

同样的事情（无限循环，但如果你用完钱就会中断，没有递归调用），

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

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+=and-=作为加法/减法和赋值的快捷方式，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)
