Python control keyboard and mouse: pynput

Address: https://pypi.python.org/pypi/pynput

This library allows you to control and monitor input devices.

For each input device, it contains a sub package to control and monitor the input device:

• pynput.mouse: a class that controls and monitors the mouse or touchpad.

• pynput.keyboard: a class that contains the control and monitoring keyboard.

Introduction to basic usage:

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))

#Mouse movement (x,y) distance
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()

#Press and release space
keyboard.press(Key.space)
keyboard.release(Key.space)

#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 monitoring:

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()
