[Python] Detect press of alt key with pynput keyboard

I am trying to hold down the alt key when I press it with pynput. I checked the documentation and could not find a list saying how to call all specific keys or detect all specific keys. So that sucks.

I've used their cookie-cutter code for detecting presses to try and detect keys:

from pynput.keyboard import Key, Listener

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

def on_release(key):
print('{0} release'.format(
key))
if key == Key.esc:
# Stop listener
return False

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


but when I try to modify it like this...

from pynput import keyboard

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

def on_release(key):
print('Key released: {0}'.format(
key))
if key == keyboard.Key.alt_1: <------ this
print('test')

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


It just quits when I attempt to press alt or any key I select for the if statement.

Ideally, I'd like to do this:

from pynput import keyboard

def on_release(key):
if key == keyboard.Key.alt_1:
keyboard.press.alt_1

# Collect events until released
with keyboard.Listener(on_release=on_release) as listener:
listener.join()


but obviously, I can't even reach this point. Help?
