我正在尝试使用PyQt5创建一个简单的应用程序，并且试图设置一个标签来显示每0.01秒的时间，但是一小段时间后它就会停止。
当我使用print(self.label_9.text())时，循环不会停止。我看到该软件改变了它的价值，但是当我看屏幕时，标签只是没有变化。
这是我所有的代码（类中的计时器函数是计时器）：

from datetime import datetime

def extract(string) :
string = string[12:]
spliter = string.split(':')
hours = int(spliter[0])
minutes = int(spliter[1])
spliter = spliter[2].split('.')
seconds = int(spliter[0])
miliseconds = int(spliter[1])
return hours,minutes,seconds,miliseconds
