Python，def没有看到变量

  • 772

大家好，煎蛋，有这么一个问题，我正在做一个关于赌场的游戏

import random
import time
import os
balance = 555
def game():
    game = input('Ваша ставка $ --')
    if int(game) > int(balance):
        print('Error')
    game2 = random.randint(0,5)
    game3 = input('Ваше число от 1 до 5 X -- ')
    if game3 == game2:
        print('Вы вииграли X -- ')
        game = int(game) * 2
        balance = int(game) + int(balance)
        print(str(balance))
    else:
        print('Проигрыш :(')
        balance = int(balance) - int(game)
        print(str(balance))


while 1:
    cmd = input('X -- ')
    if cmd == 'casino':
        game()
    elif cmd == 'end':
        break

但是，当我运行它时，会发生以下错误

Traceback (most recent call last):
  File "e:\VSC\pyvsc\hack.py\hacktest.py", line 25, in <module>
    game()
  File "e:\VSC\pyvsc\hack.py\hacktest.py", line 7, in game
    if int(game) > int(balance):
UnboundLocalError: local variable 'balance' referenced before assignment

变量balance存在，但 def 没有看到它

  1. Best Answer
    balance = 555
def game(balance):
    return balance

game(balance)

  2. 可变余额不在游戏功能范围内

    如果需要更改 balance 变量，请在函数内部添加全局 balance ，使其成为全局。

    import random
import time
import os
balance = 555
def game():
    global balance  # <------
    game = input('Ваша ставка $ --')
