Question

我在带有键盘库的python中使用键侦听器。但是我得到一个错误。我不明白为什么。此功能概括如下：
我随机选择一个数字。然后，我从oruntu列表中随机选择一个数字。像这样处理：
随机数：40
从oruntu中随机选择数字：-1
40 + =（-1）
39 + =（-1）
38 + =（-1）
然后，如果我按了正确的键，则意味着“ f”键，再次启动function2。然后再次重复，直到我按下“ esc”键。

def function2():
    keys = {"a": -4, "s":-3, "d":-2 , "f":-1, "esc":0}
    oruntu = [-4,-3,-2,-1]
    sayi = random.randrange(0,99)
    randChoice = choice(oruntu)
    toplam = sayi
    while(True):
        b = randChoice
        toplam += randChoice
        print(toplam)
        def listen(key):
            while True:
                keyboard.wait(key) 
                if(keys[key]== randChoice):
                    function2()
                if(keys[key]== 0):
                    break
        threadss = [Thread(target=listen, kwargs={"key":key}) for key in keys]
        for thread in threadss:
            thread.start()
        sleep(0.5)
t = threading.Thread(target=function2)
t.start()

错误：

Python线程和键侦听器使用。我遇到错误了。为什么？
