dll = ctypes.WinDLL('user32.dll')
dll.LockWorkStation()
time.sleep(1)

keyboard.send('enter')

Answer 1

For anyone still looking for a solution, there is none (in python)

Both unfortunately and fortunately, Windows blocks software keyboard input in the passcode/password screen to prevent automated scripts from controlling the PC. The few ways you can unlock Windows programmatically, is to either emulate a physical keyboard, or use a lower-level language such as C, C++ or C#
