赋值前引用的局部变量“gamebot”

Question

这是我的问题:) 我的问题很直接，第一个程序是正确的程序但第二个程序不是，为什么？

gamebot = "OFF"

def gamebot_status():
    if gamebot == "OFF":
        gamebotTest = gamebot
        print("Gamebot is right now ", gamebotTest, "\nTurning On gamebot in... \n1 \n2 \n3 \n\n", sep='')
        gamebotTest = "ON"
        print("====================\nGamebot Status = ", gamebotTest, "\n====================", sep='')
    else:
        pass
        
gamebot_status()

gamebot = "OFF"

def gamebot_status():
    if gamebot == "OFF":
        gamebotTest = "OFF"
        print("Gamebot is right now ", gamebotTest, "\nTurning On gamebot in... \n1 \n2 \n3 \n\n", sep='')
        gamebotTest = "ON"
        print("====================\nGamebot Status = ", gamebotTest, "\n====================", sep='')
    else:
        pass
        
gamebot_status()

唯一不同的是第 4 行

gamebotTest = gamebot

&

gamebotTest = "OFF"

问候

我期待这两个程序产生相同的结果。因此，请纠正我🙏

欢迎来到 Stackoverflow，Inferno！

为了访问最顶层作用域中的变量，您需要在函数顶部添加一个

global gamebot

（def）。

您更正后的代码将是：

gamebot = "OFF"

def gamebot_status():
    global gamebot

    if gamebot == "OFF":
        gamebotTest = "OFF"
        print("Gamebot is right now ", gamebotTest, "\nTurning On gamebot in... \n1 \n2 \n3 \n\n", sep='')
        gamebotTest = "ON"
        print("====================\nGamebot Status = ", gamebotTest, "\n====================", sep='')
    else:
        pass
        
gamebot_status()
