How to close a cmd window using python 2.7

Question

The title pretty much says it, although it does not need to be specific to a cmd, just closing an application in general. I have seen

os.system(taskkill bla         


        

Answer 1

Here is an approach that uses the Python for Windows extensions (pywin32) to find the PIDs and taskill to end the process (based on this example). I went this way to give you access to some extra running information in case you didn't want to indiscriminately kill any cmd.exe:

import os
from win32com.client import GetObject

WMI = GetObject('winmgmts:')
processes = WMI.InstancesOf('Win32_Process')

for p in WMI.ExecQuery('select * from Win32_Process where Name="cmd.exe"'):
    print "Killing PID:", p.Properties_('ProcessId').Value
    os.system("taskkill /pid "+str(p.Properties_('ProcessId').Value))

Now inside that for loop you could peek at some other information about each running process (or even look for child processes that depend on it (like running programs inside each cmd.exe). An example of how to read each process property might look like this:

from win32com.client import GetObject

WMI = GetObject('winmgmts:')
processes = WMI.InstancesOf('Win32_Process')

for p in WMI.ExecQuery('select * from Win32_Process where Name="cmd.exe"'):
    print "--running cmd.exe---"
    for prop in [prop.Name for prop in p.Properties_]:
        print prop,"=",p.Properties_(prop).Value

Answer 2

something like this?

import sys
sys.exit()

or easier ...

raise SystemExit

if that's not what your looking for tell me

also you can just save the file with a .pyw and that doesn't open the cmd at all

Answer 3

I used this to terminate and close the cmd window, hope it help os.system("taskkill /f /im cmd.exe")

Answer 4

For anyone who's stuck with Python 2.7 and unable to download pywin32 thanks to red tape in your organization. If you're on Windows XP and above you can use taskkill to kill the process by window title name like below for a dos command prompt that was started in elevated mode with title MyTitle

os.system('taskkill /fi "WindowTitle eq Administrator: MyTitle"')

Answer 5

the exit() command works however in 2.7 it still asks you if you are sure you want to quit. It states that the program is still running. ETC
