How to create Python event that should invoke on before windows sleep mode

Question

I need Python event that should log present time into a file when windows receive sleep request. Below is my main code,

import subprocess

# Here code required to log the time at which system going to sleep
command = 'Sleep.py'
# Some usefull stuff
if subprocess.call(command, shell=True):
    print 'Success'
else:
    print 'Fail'

Below is 'Sleep.py' code,

import os
os.system("Rundll32.exe Powrprof.dll,SetSuspendState Sleep")

Can any one please provide solution to this

AFAIK, there is no simple way to do this. You will need to listen for the WM_POWERBROADCAST message. you can see some kind of examples here: https://stackoverflow.com/questions/1411186/python-windows-shutdown-events — Jacobr365, May 09 '18 at 16:04

Moved to answer as requested by asker.

As far as I know, there is no simple way to do this. You will need to listen for the WM_POWERBROADCAST message. You can see an example of listening for the shutdown event here: shutdown example

It should be similar except you are listening for WM_POWERBROADCAST with PBT_APMSUSPEND.

You can read about WM_POWERBROADCAST Here
