使 pynput 鼠标侦听器减少资源消耗

Question

我正在尝试使用pynput 中的此脚本来监视我的鼠标，但它太占用资源了。尝试import time添加time.sleep(1)后on_move(x, y)功能，但当你运行它时，你的鼠标会发疯。这是整体代码：import timedef on_move(x, y):    print('Pointer moved to {0}'.format((x, y)))    time.sleep(1) # <<< Tried to add it over here cuz it takes most of the process.def on_click(x, y, button, pressed):    print('{0} at {1}'.format('Pressed' if pressed else 'Released', (x, y)))    if not pressed:        return Falsedef on_scroll(x, y, dx, dy):    print('Scrolled {0}'.format((x, y)))with Listener(on_move=on_move, on_click=on_click, on_scroll=on_scroll) as listener:    listener.join()

当执行某些会阻止代码的任务时，您可以使用线程来运行代码。（在您的代码中，sleep(1)将阻止代码），无论如何，这在我的电脑上运行良好：

from pynput.mouse import Listener

import time

import threading

def task(): # this is what you want to do.

    time.sleep(1)  # <<< Tried to add it over here cuz it takes most of the process.

    print("After sleep 1 second")

def on_move(x, y):

    print('Pointer moved to {0}'.format((x, y)))

    threading.Thread(target=task).start() # run some tasks here.

def on_click(x, y, button, pressed):

    print('{0} at {1}'.format('Pressed' if pressed else 'Released', (x, y)))

    if not pressed:

        return False

def on_scroll(x, y, dx, dy):

    print('Scrolled {0}'.format((x, y)))

with Listener(on_move=on_move, on_click=on_click, on_scroll=on_scroll) as listener:

    listener.join()
