Help to make a shuffleboard scoreboard

Please wrap code in Python tags.

app.exec_() blocks program execution until the GUI is closed.

sys.exit(app.exec_()) exits the program as soon as this happens.

This is never executed:

button1 = Button(2)
button2 = Button(3)
button3 = Button(4)

while True:
    if button3.is_pressed:
        count += 1
        sleep(0.4)
    if button1.is_pressed:
        count1 += 1
        sleep(0.4)
    elif button2.is_pressed:
        count = 0
        count1 = 0

Read up on QTimer to see how you can run your GUI and run your hardware code simultaneously.

Using a sleep(0.4) to prevent a button press from being counted as multiple presses is not reliable. You never want to use the sleep() command in a gui application. It makes the GUI unresponsive.
