如何停止/跳出線程無限的while循環？

Question

我需要通過 stop_button function 停止 while 循環。 嘗試了幾種方法，但都失敗了。 求指點，謝謝。

def start_button():
    t1 = threading.Thread(target=thread1)
    t1.start()

def thread1():
    while True:
        start()

def stop_button():
    pass

Answer 1

也許這

flag = False

def start_button():
    flag = True
    t1 = threading.Thread(target=thread1)
    t1.start()

def thread1():
    while flag:
        start()

def stop_button():
    flag = false
