On some systems keyboard can repeate sending key event when it is pressed so with pynput
you would need only this (for key ‘a’)
from pynput.keyboard import Listener, KeyCode
def get_pressed(event):
#print('pressed:', event)
if event == KeyCode.from_char('a'):
print("hold pressed: a")
with Listener(on_press=get_pressed) as listener:
listener.join()
But sometimes repeating doesn’t work or it need long time to repeate key and they you can use global variable for key to keep True/False
from pynput.keyboard import Listener, KeyCode
import time
# --- functions ---
def get_pressed(event):
global key_a # inform function to use external/global variable instead of local one
if event == KeyCode.from_char('a'):
key_a = True
def get_released(event):
global key_a
if event == KeyCode.from_char('a'):
key_a = False
# --- main --
key_a = False # default value at start
listener = Listener(on_press=get_pressed, on_release=get_released)
listener.start() # start thread with listener
while True:
if key_a:
print('hold pressed: a')
time.sleep(.1) # slow down loop to use less CPU
listener.stop() # stop thread with listener
listener.join() # wait till thread ends work
solved Python Code that returns true while key is pressed down false if release?
