def on_release(key):
    print('{} 释放了'.format(key))
    if key == keyboard.Key.esc:

from pynput import keyboard
# 监听键盘键入
with keyboard.Events() as events:
    for event in events:

        # 监听esc键，释放esc键，停止监听。
        if event.key == keyboard.Key.esc:
            print('接收到事件 {}, 停止监听'.format(event))
            break
        else:
            if isinstance(event, keyboard.Events.Press):
                print('按下按键 {} '.format(event))
            elif isinstance(event, keyboard.Events.Release):
