How to Generate Keyboard Events Using Python
Python offers various techniques to simulate keyboard events, enabling you to interact with your computer's keyboard actions programmatically.
Simulating Keystrokes
For a direct and cross-platform approach, consider using the ctypes library, which allows you to interact with the Windows API:
Example:
import ctypes
from ctypes import wintypes
import time
user32 = ctypes.WinDLL('user32', use_last_error=True)
VK_A = 0x41 # Virtual key code for 'A'
KEYEVENTF_KEYUP = 0x0002 # Key event flag for key release
class KEYBDINPUT(ctypes.Structure):
_fields_ = (("wVk", wintypes.WORD),
("wScan", wintypes.WORD),
("dwFlags", wintypes.DWORD),
("time", wintypes.DWORD),
("dwExtraInfo", wintypes.ULONG_PTR))
def press_key(key_code):
key_input = KEYBDINPUT(wVk=key_code)
user32.SendInput(1, ctypes.byref(key_input), ctypes.sizeof(key_input))
def release_key(key_code):
key_input = KEYBDINPUT(wVk=key_code, dwFlags=KEYEVENTF_KEYUP)
user32.SendInput(1, ctypes.byref(key_input), ctypes.sizeof(key_input))
# Press and release the 'A' key
press_key(VK_A)
time.sleep(1)
release_key(VK_A)
