How can I use KivyMD to execute a py script and get the pid of the script?

[Dean-O Rochester]

Hi all

I have a  kivymd program where I would like to execute a python3 script and get the pid of the python3 script I execute so I can use a button in my kivyMD app to kill the process

Thanks in advance for your time

This is independent of Kivy or KivyMD, check out Python's subprocess.

Running a Python script like this will not work on mobile.

Hi

I am running this on a raspberry pi not mobile. 

So is this possible to get the pid of the executed script

Here is something to get you started.  Use subprocess.Popen() https://docs.python.org/3/library/subprocess.html#popen-constructor to launch the child process.  It returns a Popen object, the pid attribute is the pid of the child process.  https://docs.python.org/3/library/subprocess.html#subprocess.Popen.pid
