Python имитирует keydown
После нескольких часов работы, я задаюсь вопросом, можно ли имитировать нажатие клавиши на клавиатуре. Например, я хочу, чтобы моя программа удерживала клавишу «x» в течение пяти секунд, поэтому, когда я запустил ее в блокноте, было бы похоже на следующее: xxxxxxxxxxxxx . Я пробовал использовать различные фрагменты кода в Интернете, лучшее, что я мог найти до сих пор:
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]
Модуль Sendkey не решает мою проблему либо потому, что он позволяет вам отправлять только одно нажатие, а не событие закрытия. Я знаю об аутоите, использовал его в прошлом, но я просто хочу знать, возможно ли это с помощью python и как. PS Я использую python для окон
- Имитация ключевого события с помощью Python для Linux
- Определить длину нажатия клавиши python
- Как обнаружить нажатие клавиши ESCape в Python?
- Имитировать Python нажатия клавиш для управления игрой
- Проверьте, нажата ли клавиша с помощью python (демона в фоновом режиме)

Этот код должен начать работу. ctypes используется сильно. Внизу вы увидите пример кода.

Если вы используете Python для Windows, то есть очень хороший шанс, что у вас есть модуль win32api , который обрабатывает подключение к API для вас …
>>> import win32api >>> import win32con >>> win32api.keybd_event(win32con.SHIFT_PRESSED, 0, win32con.KEYEVENTF_EXTENDEDKEY, 0) >>> HELLO
Это помогает? (ps вы должны установить IPython, если это вообще возможно, это очень полезно для экспериментов)
Я знаю, что этот вопрос действительно старый, но я нашел хорошую библиотеку: PyUserInput . Я не уверен, как загрузить его в windows (я давно не загружал библиотеки для окон). В linux легко просто загрузить pip (если вы этого не сделали): sudo apt-get install pip а затем sudo pip install pyuserinput . И тогда код действительно прост:
#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')
Я изменил ответ Noctis для работы с символами Unicode.
