PyQt5 QTimer count until specific seconds

问题

I am creating a program in python and i am using pyqt. I am currently working with the QTimer and i want to print "timer works" every seconds and stop printing after 5 seconds. Here is my code:

timers = []
def thread_func():
    print("Thread works")
    timer = QtCore.QTimer()
    timer.timeout.connect(timer_func)
    timer.start(1000)
    print(timer.remainingTime())
    print(timer.isActive())
    timers.append(timer)

def timer_func():
    print("Timer works")

Below is a simple demo showing how to create a timer that stops after a fixed number of timeouts.

from PyQt5 import QtCore

def start_timer(slot, count=1, interval=1000):
    counter = 0
    def handler():
        nonlocal counter
        counter += 1
        slot(counter)
        if counter >= count:
            timer.stop()
            timer.deleteLater()
    timer = QtCore.QTimer()
    timer.timeout.connect(handler)
    timer.start(interval)

def timer_func(count):
    print('Timer:', count)
    if count >= 5:
        QtCore.QCoreApplication.quit()

app = QtCore.QCoreApplication([])
start_timer(timer_func, 5)
app.exec_()
