我在哪里放置我的作业？

Question

我创建了一个程序，您可以在其中根据帐户密码“破解”虚假银行帐户以获取资金。我将money 指定为 0（因为游戏是每次打开时都会重新启动的游戏类型），将lives 指定为 100，因为您有 100 条生命来获得尽可能多的钱。代码如下：

#PASSWORD GUESSING MONEY GAME
#
#
#
#
import random
import time

print('Hello, please enter a name for your bank account.')
bank_acc = input()
print('Welcome to your bank account: ' + bank_acc)
print("$$$: 0")
print('Just press ENTER when ready.')
print('At the press of a button, you will have access to hundreds of millions of bank accounts.')
print('But do not be so quick, you will be required to hack the password of each bank account.')
print('Each and every password is a 3-digit code.')
print('You have 100 lives to do so. Each time you get the password wrong, subtracts a life')
print('After you use up all 100 lives, your bank account will be reset.')
print('Good luck') 

money = 0
lives = 100

def game():
    passwords = random.randint(100, 999)

    while lives <= 100:
        print('Take a guess')
        guess = input()
        guess = int(guess)

        if guess < passwords:
            print('Password incorrect. Number too low.')
            lives = lives - 1

        if guess > passwords:
            print('Password incorrect. Number too high')
            lives = lives -1

        if guess == passwords:
            break

    if guess == passwords:
        money = money + passwords
        print('Hacking account...')
        time.sleep(1)
        print('.')
        time.sleep(1)
        print('.')
        time.sleep(1)
        print('.')
        print('Account hacked.')
        print('...Adding money to account...')
        print('Your Account:')
        print('$$$: ' + str(money))
        print('Lives: ' + str(lives))
        print('...NEXT ACCOUNT...')
        print('')
        print('')
        time.sleep(2)
        game()
game()

当它说在分配之前引用了lives。我知道，由于lives 没有在具有while lives <= 100: 的代码块中分配，但是我可以在哪里放置分配以在引用它之前进行分配。我知道你可以把它放在哪里，但是......如果有人猜对了密码，我不想在进入下一个帐户时将钱重置回 0 并且将生命重置回 100。请帮忙，谢谢！！！

Answer 1

Python 的函数是function scoped。因此，您需要在函数定义中但在 while 循环之前放置生命，然后再引用它。另一方面，您可以显式声明它以引用程序中声明的全局版本的生命。或者，您可以将游戏定义为具有传递然后分配的参数，称为“生命”。

Answer 2

您需要将全局变量移动到容器类中。在构造函数中初始化它们（下面的__init__ 方法），而不是从内部调用game，而是创建一个每次都创建一个新游戏的外部循环。

class Game(object):
    def __init__(self):
        self.lives = 100
        self.money = 0

    def run(self):
        password = random.randint(100, 999)
        while self.lives < 100:
           ...
        ...
        time.sleep(2)
        # game()

while True:
    g = Game()
    g.run()
