python使用笔记：pynput库控制键盘鼠标

Posted 2022-01-06 丘木木

pynput这个库让你可以控制和监控输入设备。

对于每一种输入设备，它包含一个子包来控制和监控该种输入设备：

• pynput.mouse：包含控制和监控鼠标或者触摸板的类。
• pynput.keyboard：包含控制和监控键盘的类。

基本用法介绍：

from pynput.mouse import Button, Controller
import time 

#获取当前鼠标位置
mouse = Controller()
print(mouse.position)
time.sleep(3)
print('The current pointer position is 0'.format(mouse.position))

#设置鼠标位置
mouse.position = (277, 645)
print('now we have moved it to 0'.format(mouse.position))

#鼠标移动（x,y）个距离
mouse.move(5, -5)
print(mouse.position)

mouse.press(Button.left)
mouse.release(Button.left)

#Double click
mouse.click(Button.left, 1)

#scroll two steps down
mouse.scroll(0, 500)

监控鼠标事件 ：

from pynput import mouse

def on_move(x, y ):
    print( 'Pointer moved to o'.format((x,y)) )

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 at 1'.format('down' if dy < 0 else 'up',(x, y)))

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

键盘输入用法：

from pynput.keyboard import Key, Controller

keyboard = Controller()
# 按下空格和释放空格
#Press and release space
keyboard.press(Key.space)
keyboard.release(Key.space)
# 按下a键和释放a键
#Type a lower case A ;this will work even if no key on the physical keyboard is labelled 'A'
keyboard.press('a')
keyboard.release('a')

#Type two upper case As
keyboard.press('A')
keyboard.release('A')
# or 
with keyboard .pressed(Key.shift):
 keyboard.press('a')
 keyboard.release('a')

#type 'hello world ' using the shortcut type method
keyboard.type('hello world')

键盘监听：

from pynput import keyboard

def on_press(key):
 try:
  print('alphanumeric key 0 pressed'.format(key.char))
 except AttributeError:
  print('special key 0 pressed'.format(key))

def on_release(key):
 print('0 released'.format(key))
 if key == keyboard.Key.esc:
  return False

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