按下鼠标按钮后，如何使程序不会无限循环运行

Question

So I'm trying to make the program not run in an endless loop once pressed is true and check for when the mouse button is released and stop the while loop.

from pynput import mouse
from pynput.mouse import Button, Controller
import time
m = Controller()


def on_click(x, y, button, pressed):
    print('Pressed' if pressed else 'Released')

    while (pressed):
        m.move(0, 1)
        time.sleep(.001)

with mouse.Listener(
        on_click=on_click) as listener:
    listener.join()

Answer 1

Something like this. Don't try to sleep for 1ms, you'll waste too many resources.

from pynput import mouse
from pynput.mouse import Button, Controller
import time
m = Controller()

mousedown = False


def on_click(x, y, button, pressed):
    global mousedown
    print('Pressed' if pressed else 'Released')
    mousedown = pressed

listener = mouse.Listener(on_click=on_click) 

while True:
    if mousedown:
        m.move( 0, 1 )
    time.sleep( 0.1 )
