How to Close a program using python?

Question

Is there a way that python can close a windows application (example: Firefox) ?

I know how to start an app, but now I need to know how to close one.

Answer 1

In order to kill a python tk window named MyappWindow under MS Windows:

from os import system
system('taskkill /F /FI "WINDOWTITLE eq MyappWindow" ')

stars maybe used as wildcard:

from os import system 
system('taskkill /F /FI "WINDOWTITLE eq MyappWind*" ')

Please, refer to "taskkill /?" for additional options.
