Python 3.x - Getting the state of caps-lock/num-lock/scroll-lock on Windows

问题

Just as the question asks, I know this is possible on Linux, but I couldn't find anything recent for Windows. Is it even possible?

回答1:

You can use ctypes to load user32.dll and then call GetKeyState with nVirtKey = VK_CAPITAL (0x14)

def get_capslock_state():
    import ctypes
    hllDll = ctypes.WinDLL ("User32.dll")
    VK_CAPITAL = 0x14
    return hllDll.GetKeyState(VK_CAPITAL)

回答2:

Install pywin32 for Python 3.x

Here is the example for checking capslock state.

from win32api import GetKeyState 
from win32con import VK_CAPITAL 
GetKeyState(VK_CAPITAL)
