Py 中的老虎机游戏

Question

我正在用 python 构建一个非常基本的老虎机。这是我正在做的第一个 python 代码，并且正在遵循 ytb 教程。不知何故，当我测试代码时，我在终端中没有得到正确的结果。

MAX_LINES = 3

def deposit():
    while True:
        amount = input("What would you like to deposit? $")
        if amount.isdigit():
            amount = int(amount)
            if amount > 0:
                break
            else:
                print("Amount must be greater than 0.")
        else:
                    print("Please enter a number.")

                    return amount



def get_number_of_lines():
      while True:
        lines = input("Enter the number of lines to bet on (1-" + str(MAX_LINES) + ")? ")
        if lines.isdigit():
            lines = int(lines)
            if 1 <= lines <= MAX_LINES:
                break
            else:
                print("Enter a valid number of lines.")
        else:
                    print("Please enter a number.")

                    return lines


def main():
    balance = deposit()
    lines = get_number_of_lines()
    print(balance, lines)

main()

这是我到目前为止编写的代码。

这是我在终端中得到的内容（我在 VsCode 中执行此操作）。

What would you like to deposit? $200

Enter the number of lines to bet on (1-3)? 3

None None. \<\<this should say 3 ... 

而且我还没有得到，但找到这个问题的答案很困难，YouTube 视频下还有其他一些人在终端中遇到相同的输出。

Answer 1

您需要正确缩进

return ...

行：

MAX_LINES = 3

def deposit():
    while True:
        amount = input("What would you like to deposit? $")
        if amount.isdigit():
            amount = int(amount)
            if amount > 0:
                break
            else:
                print("Amount must be greater than 0.")
        else:
                    print("Please enter a number.")

    return amount

def get_number_of_lines():
      while True:
        lines = input("Enter the number of lines to bet on (1-" + str(MAX_LINES) + ")? ")
        if lines.isdigit():
            lines = int(lines)
            if 1 <= lines <= MAX_LINES:
                break
            else:
                print("Enter a valid number of lines.")
        else:
                    print("Please enter a number.")

    return lines

def main():
    balance = deposit()
    lines = get_number_of_lines()
    print(balance, lines)

main()
