How to make a python script that can exit the system, shut down and restart the computer?

Question

Background

I am currently participating in python, and I thought that it would be a very cool project to have a kind of "control center" in which I could turn off, restart and exit my computer. I also want to use the subprocess module, since I heard that the import operating system module is out of date.

Current code

def shutdown(self): import subprocess subprocess.call(["shutdown", "-f", "-s", "-t", "60"]) 

Question

I'm really asking if there is a way (using the subprocess module) to log out and restart the computer?

Specifications

Python 2.7.3

Windows 7 32 bit

Answer 1

To restart:

 shutdown /r 

To log out:

 shutdown /l 

End code block (on request):

Sign Out:

 def shutdown(self): import subprocess subprocess.call(["shutdown", "-f", "-s", "-t", "60"]) 

Restart:

 def shutdown(self): import subprocess subprocess.call(["shutdown", "-f", "-r", "-t", "60"]) 

Answer 2

First you must:

 import subprocess 

To turn off your Windows computer:

 subprocess.call(["shutdown", "/s"]) 

To restart a Windows computer

 subprocess.call(["shutdown", "/r"]) 

To exit a Windows PC:

 subprocess.call(["shutdown", "/l "]) 

To turn off a Windows computer after 900 s:

 subprocess.call(["shutdown", "/s", "/t", "900"]) 

To abort the shutdown, because there is no good reason to shut down the computer using a Python script, you simply copied the code from stackoverflow:

 subprocess.call(["shutdown", "/a "]) 

I just tried these function calls in Python 3.5. Firstly, I don’t think that this has changed since Python 2.7, and secondly: this is 2016, so I think you made the transition after you asked this question.

Answer 3

If you cannot get shutdown to work somehow, you can always just call the function that it calls from the USER library. You can do this with ctypes or win32api , but you can also just do this:

 subprocess.call(['rundll32', 'user.exe,ExitWindowsExec') 

Or you can call a higher-level shell function that the launch menu uses:

 subprocess.call(['rundll32', 'shell32.dll,SHExitWindowsEx 2') 

(See the documentation for these features on MSDN.)

I think this is probably the worst way to do this. If you want to run the command, run shutdown ; if you want to use the API use win32api . But if you have a fancy system where shutdown /r just doesn't work, this is an option.
