Python simuler keydown
après plusieurs heures de recherche, je me demande s'il est possible de simuler une pression sur le clavier. Par exemple, je veux que mon programme maintienne la touche x enfoncée pendant cinq secondes. J'ai essayé autour des morceaux de code sur internet, la meilleure chose que j'ai pu trouver jusqu'à présent, c'est:
import ctypes
import time
user32 = ctypes.windll.user32
inputhex = raw_input("Please enter your desired key's code (HEX): ")
keycode = int(inputhex, 16)
time.sleep(1)
#VOID keybd_event(BYTE bVk, BYTE bScan, DWORD dwFlags, PTR dwExtraInfo);
user32.keybd_event(keycode,0,2,0) #is the code for KEYDOWN
time.sleep(5)
#user32.keybd_event(keycode,0,0,0) #is the code for KEYDUP[/code]
le module Sendkey ne résout pas mon problème soit parce qu'il ne vous permet d'envoyer qu'une seule pression de touche et pas un événement clé de maintien vers le bas. Je sais que sur autoit, utilisé dans le passé, mais je veux vraiment savoir si c'est possible avec python et comment. P.S. j'utilise python Pour windows

si vous utilisez Python Pour Windows, il y a de fortes chances que vous ayez le module win32api , qui gère le branchement à L'API pour vous...
>>> import win32api
>>> import win32con
>>> win32api.keybd_event(win32con.SHIFT_PRESSED, 0, win32con.KEYEVENTF_EXTENDEDKEY, 0)
>>> HELLO
est-ce que ça aide? (p. S. vous devriez installer IPython si possible, il est massivement utile pour expérimenter)

je sais que cette question est très ancienne, mais j'ai trouvé une belle bibliothèque: PyUserInput .
Je ne suis pas sûr de savoir comment le télécharger dans windows(je n'ai pas Téléchargé de bibliothèques pour windows depuis longtemps). Sous linux, il suffit de télécharger pip(si vous ne l'avez pas fait): sudo apt-get install pip et ensuite sudo pip install pyuserinput .
Et puis le code est très simple:
#imports the library
from pykeyboard import PyKeyboard
#import the sleep function
from time import sleep
#initialize the keyboard simulator
keyboard = PyKeyboard()
#presses the key
keyboard.press_key('x')
#waits five seconds before releasing the key
sleep(5)
#releases the key
keyboard.release_key('x')
