Using Mouse and Keyboard Listeners Together in Python

I have been using pynput library for monitoring the clicks of the mouse.The only problem I am facing is that the terminal does not terminate on pressing Ctrl+C. I need to use keyboard listener with mouse listener. Here's my code:

import os
import time
import re
from pynput import mouse
from pynput.keyboard import Key, Listener
f=open('maniac1.txt','a')

inc=1
f.write('<mouse_new>\n')

def on_click(x, y, button, pressed):
    f=open('maniac1.txt','a')
    if button == mouse.Button.left:
        print 'Left'
        f.write('left\n')

    if button == mouse.Button.right:
        print 'right'
        f.write('right\n')
    if button == mouse.Button.middle:
        print 'middle'
        f.write('middle\n')

with mouse.Listener(on_click=on_click,on_scroll=on_scroll) as listener:
    try:
        listener.join()
    except MyException as e:
        print('Done'.format(e.args[0]))

How can i terminate this code after pressing Esc or Ctrl+C?I am using OSX.

I've just finished the same thing a few hours ago, here is what I wrote.

First add another keyboard listener:

# Collect events until released
with keyboard.Listener(on_release=on_release) as k_listener, \
        mouse.Listener(on_click=on_click) as m_listener:
    k_listener.join()
    m_listener.join()

Then add the on_release function:

def on_release(key):
    if key == keyboard.Key.esc:
        # Stop listeners
        m_listener.stop()
        return False

Then if you press Esc this code will be terminate.

For OSX you need to run python with sudo or it won't work fine.

This code using mouse and keyboard listeners together.

from pynput.keyboard import Listener  as KeyboardListener
from pynput.mouse    import Listener  as MouseListener
from pynput.keyboard import Key
import logging

logging.basicConfig(filename=("log.txt"), level=logging.DEBUG, format='%(asctime)s: %(message)s')

def end_rec(key):
    logging.info(str(key))

def on_press(key):
    logging.info(str(key))

def on_move(x, y):
    logging.info("Mouse moved to ({0}, {1})".format(x, y))

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

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


with MouseListener(on_click=on_click, on_scroll=on_scroll) as listener:
    with KeyboardListener(on_press=on_press) as listener:
        listener.join()

Create an instance keyboard.Listener without "with" keyword so that you can start and stop the listener based on your mouse listener. Check the below code which will stop listening to key-press of f8 after right click by mouse.

import os
import time
import re
from pynput import mouse
from pynput.keyboard import Key, Listener
#f=open('maniac1.txt','a')

inc=1
#f.write('<mouse_new>\n')
from pynput import keyboard

def on_functionf8(key):
    if (key==keyboard.Key.f8):
        print('f8 is pressed')


key_listener = keyboard.Listener(on_release=on_functionf8)
key_listener.start()


def on_click(x, y, button, pressed):
    f=open('maniac1.txt','a')
    if button == mouse.Button.left:
        print ('Left')
        #f.write('left\n')

    if button == mouse.Button.right:
        key_listener.stop()
        print ('right')
        #f.write('right\n')
    if button == mouse.Button.middle:
        print ('middle')
        #f.write('middle\n')

with mouse.Listener(on_click=on_click) as listener:
    try:
        listener.join()
    except MyException as e:
        print('Done'.format(e.args[0]))

run the program and press f8 and you will see 'f8 is pressed' on the terminal. But right click and press f8. You wont see anything printed as we stopped the keyboard listener on right click of mouse.

for mac:

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



key_listener = keyboard.Listener(on_release=on_press)

only few keys like cmd, alt are listened on mac by default.
