一次两个库

Question

Hey guys I am trying to make something like a keylogger I am currently using the pynput library but the problem is the program always executes the last thing I have imported for example if I import mouse listener first it doesn't catch the keyboard or the other way around so is there a way I can use both libraries at the same time?

from pynput.keyboard import Key, Listener
from pynput.mouse import Listener


def on_press(key):
    print('{0} pressed'.format(
        key))

def on_release(key):
    print('{0} release'.format(
        key))

def on_move(x, y):
    print('Pointer moved to {0}'.format(
        (x, y)))

def on_click(x, y, button, pressed):
    print('{0} at {1}'.format(
        'Pressed' if pressed else 'Released',
        (x, y)))

def on_scroll(x, y, dx, dy):
    print('Scrolled {0}'.format(
        (x, y))),

# Collect events until released
with Listener(on_move=on_move, on_click=on_click, on_scroll=on_scroll, on_press=on_press, on_release=on_release) as listener:
    listener.join()

Answer 1

In Python, you can import things like this:

from pynput.keyboard import Key, Listener as keyListener
from pynput.mouse import Listener as mouseListener

When you need to use Listener from the mouse library, just use mouseListner instead and when you need to use Listener from the keyboard library, just use keyListner instead.

Hope this helps!

Answer 2

You are importing the name Listener twice. The second time, it will overwrite the previous Listener. I suggest doing something like:

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

You will have to use MouseListener and KeyboardListener to refer to them.

Answer 3

from pynput.keyboard import Key, Listener
from pynput.mouse import Listener

The second line overwrites the name Listener in the global name space. One way to fix this is

from pynput import keyboard, mouse

Now you have to refer to keyboard.Listener or mouse.Listener . You will also need to do keyboard.Key instead of just Key .
