python中库pynput的用法

pynput是一个Python库，用于控制和监视输入设备，如鼠标和键盘。以下是一些pynput库的用法示例：

1. 监视键盘输入：

from pynput import keyboard

def on_press(key):
    try:
        print('Key {} pressed.'.format(key.char))
    except AttributeError:
        print('Key {} pressed.'.format(key))

def on_release(key):
    print('Key {} released.'.format(key))

with keyboard.Listener(on_press=on_press, on_release=on_release) as listener:
    listener.join()

2. 控制鼠标移动：

from pynput.mouse import Controller

mouse = Controller()

# Move the mouse relative to its current position
mouse.move(5, -5)

3. 监视鼠标输入：

from pynput import mouse

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

def on_click(x, y, button, pressed):
    if pressed:
        print('Mouse clicked at ({0}, {1}) with {2}'.format(x, y, button))

def on_scroll(x, y, dx, dy):
    print('Mouse scrolled at ({0}, {1})({2}, {3})'.format(x, y, dx, dy))

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

这些仅仅是pynput库的一些用法，还有其他的功能，如控制键盘输入、控制鼠标点击等等。
