Python 3.7+ no longer supports win32gui

[Fireflaker]

Any other way to do it?
win32api?

you can try this one ~

from ctypes import *
HWND_BROADCAST = 0xffff
WM_SYSCOMMAND = 0x0112
SC_MONITORPOWER = 0xF170
MonitorPowerOff = 2
SW_SHOW = 5
windll.user32.PostMessageW(HWND_BROADCAST, WM_SYSCOMMAND,
                           SC_MONITORPOWER, MonitorPowerOff)
shell32 = windll.LoadLibrary("shell32.dll")
shell32.ShellExecuteW(None, 'open', 'rundll32.exe',
                      'USER32', '', SW_SHOW)

pip install pywin32

worked for me on Windows 10, with python 3.10.
