现有一个PyQt5程序，当我把work函数，countTime函数及timeStop函数缩进到QThreadl类中，运行程序点击测试的时候就会提
work() takes 0 positional arguments but 2 were given
对类的理解还不是很到位，有没有大神解答一下如果把work等函数放入class中应该怎样处理才不会报错
正确代码如下：

PyQT5中 QTimer例子
import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
global sec
sec=0
class WorkThread(QThread):
trigger = pyqtSignal()
def __int__(self):
super(WorkThread,self).__init__()
def run(self):
for i in range(2000000000):
# 循环完毕后发出信号
self.trigger.emit()
def countTime():
global sec
sec += 1
# LED显示数字+1
lcdNumber.display(sec)
def work():
# 计时器每秒计数
timer.start(1000)
# 计时开始
workThread.start()
# 当获得循环完毕的信号时，停止计数
workThread.trigger.connect(timeStop)
def timeStop():
timer.stop()
print("运行结束用时",lcdNumber.value())
global sec
sec=0
if __name__ == "__main__":
app = QApplication(sys.argv)
top = QWidget()
top.resize(300,120)
# 垂直布局类QVBoxLayout
layout = QVBoxLayout(top)
# 加个显示屏
lcdNumber = QLCDNumber()
layout.addWidget(lcdNumber)
button = QPushButton("测试")
layout.addWidget(button)
timer = QTimer()
workThread = WorkThread()
button.clicked.connect(work)
# 每次计时结束，触发 countTime
timer.timeout.connect(countTime)
top.show()
sys.exit(app.exec_())
报错的代码如下：
