Basic usage Introduction:

from pynput.mouse import Button, Controller
import time 
 
mouse = Controller()
print(mouse.position)
time.sleep(3)
print('The current pointer position is {0}'.format(mouse.position))
 
 
#set pointer positon
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)

Monitor mouse events:

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()

Keyboard input usage:

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')

Keyboard Monitor:

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()
