Key Listeners in python?

keyboard

• sudo pip install keyboard
• https://github.com/boppreh/keyboard

Take full control of your keyboard with this small Python library. Hook global events, register hotkeys, simulate key presses and much more.

Global event hook on all keyboards (captures keys regardless of focus). Listen and sends keyboard events. Works with Windows and Linux (requires sudo), with experimental OS X support (thanks @glitchassassin!). Pure Python, no C modules to be compiled. Zero dependencies. Trivial to install and deploy, just copy the files. Python 2 and 3. Complex hotkey support (e.g. Ctrl+Shift+M, Ctrl+Space) with controllable timeout. Includes high level API (e.g. record and play, add_abbreviation). Maps keys as they actually are in your layout, with full internationalization support (e.g. Ctrl+ç). Events automatically captured in separate thread, doesn't block main program. Tested and documented. Doesn't break accented dead keys (I'm looking at you, pyHook). Mouse support available via project mouse (pip install mouse).

From README.md:

import keyboard

keyboard.press_and_release('shift+s, space')

keyboard.write('The quick brown fox jumps over the lazy dog.')

# Press PAGE UP then PAGE DOWN to type "foobar".
keyboard.add_hotkey('page up, page down', lambda: keyboard.write('foobar'))

# Blocks until you press esc.
keyboard.wait('esc')

# Record events until 'esc' is pressed.
recorded = keyboard.record(until='esc')
# Then replay back at three times the speed.
keyboard.play(recorded, speed_factor=3)

# Type @@ then press space to replace with abbreviation.
keyboard.add_abbreviation('@@', 'my.long.email@example.com')
# Block forever.
keyboard.wait()

I like to use Pynput, I think you can have simpler and more elegant solutions.

Many options in the official documentation: https://pypi.org/project/pynput/

• pip install pynput

Code:

from pynput import keyboard

def on_activate_a():
    print('A pressed')

def on_activate_b():
    print('B pressed')

def on_activate_c():
    print('C pressed')

def quit():
    print('QUIT')
    h.stop()

with keyboard.GlobalHotKeys({
        'a': on_activate_a,
        'b': on_activate_b,
        'c': on_activate_c,
        '<ctrl>+c': quit}) as h:
    h.join()
