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: class that controls and monitors the mouse or touchpad.

• Pynput. keyboard: contains the control and monitoring keyboard class.

Basic usage:

From pynput. mouse import Button, Controllerimport time mouse = Controller () print (mouse. position) time. sleep (3) print ('the current pointer position is {0 }'. format (mouse. position) # set pointer positonmouse. position = (277,645) print ('now we have moved it to {0 }'. format (mouse. position) # move the mouse (x, y) away from the mouse. move (5,-5) print (mouse. position) mouse. press (Button. left) mouse. release (Button. left) # Double clickmouse. click (Button. left, 1) # scroll two steps downmouse. scroll (0,500)

Monitor mouse events:

from pynput import mousedef 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 Falsedef 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, Controllerkeyboard = Controller()#Press and release spacekeyboard.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 Askeyboard.press('A')keyboard.release('A')# or with keyboard .pressed(Key.shift):    keyboard.press('a')    keyboard.release('a')#type 'hello world '  using the shortcut type  methodkeyboard.type('hello world')

 

Keyboard listening:

from pynput import keyboarddef 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 Falsewhile True:    with keyboard.Listener(        on_press = on_press,        on_release = on_release) as listener:        listener.join()
