Run python in background from other python program and continue

How to run a python program in between another python program
os.system(r'pythonw.exe D:\text.py')
I have tried this but it had pause execution between the main program
and also tried
subprocess.run(r'pythonw.exe D:\text.py')
suppose I have program text.py which notify me every hour
I have main program i.e.
code...
os.system(r'pythonw.exe D:\text.py')
code...
print("hello world")
my command should run text.py in the background and execute the following code.

You can use Python Library named "Soldier". This is very easy to use and implement.
https://pypi.org/project/soldier
import soldier
firefox_process = soldier.run('firefox', background=True)
firefox_process.pid

Python script does not execute correctly when calling another program with os.system('./myProgram')

I have a python script calling another program with the os.system command. It is a very complex program which can be called in the Terminal using ./myProgram. I want to automatically execute said program and do different stuff (which works fine) in between.
Somehow this works:
print('start')
os.system('ll')
print('end')
But calling the program with the python script:
print('start')
os.system('./myProgram')
print('end')
just executes myProgram without showing the print statements. myProgram itself displays information in the terminal.
Later I want to do more than just print something in between.
I tried using the subprocess module:
print('start')
subprocess.call('./myProgram', shell = True)
print('end')
which shows the same results as the os.system module.
Which properties of a program do not allow my python script to run properly?
And how can I call another program with my python script, execute said program and continue with the script afterwards?

u can always use a safe and secure way to call it
if u want to call app.py in the folder scripts_folder
just write:
from scripts_folder import app
Now if u have a def inside app.py for example my_def_example() u can call it by writing:
app.my_def_example()

Python: Check if Program is being closed

all.
Is there a way, using Python, to check if the script that is currently running is requested to close? For example, If I press the X-Button (close program button) on the top-right to close it, or end the script in any other way, can the script do some code before it ends? Example:
# script goes here...
if Script_To_Be_Closed: # replace this with an actual line of code.
do_stuff

There are multiple options you may use, like trapping keyboardinterrupts, but the simplest is atexit, which executes a function whenever a scripts is ended (except of a hard process kill indeed).
import atexit
def my_exit_function(some_argument):
// Your exit code goes here
print(some_argument)
if __name__ == '__main__':
atexit.register(my_exit_function, 'some argument', )
// Your script goes here

You can use a shell script to do the job
You can see the script command shown below which calls itself after executing the command to run the python file. once the python file is closed the next line will force the python command to run again. you can also customise the behaviour the way you want.
main.py
#!/bin/bash
python3 ./main.py
source ./infiniteRun.sh
If you need to stop the job just edit the file and remove the last line source ./infiniteRun.sh and save the file.

How can I stop a python script on a batch file

I want to start a python script and then automatically close that script after 2 minutes, run another command, and keep doing the same thing again like this (loop) forever :
Cd c:/location.of.script/
pythonscript.py
Stop (like ctrl+c) pythonscript.py after 120s
Del -f cookies.file
.
.
.
Is this even possible with a batch file on windows 10? If so, can someone please help me with this?
I’ve been looking everywhere but found nothing except the exit() command which stops the script from inside - this isn’t what I want to do.

You can change your python script to exit after 2 minutes, and you could batch file that has a while loop that runs forever and run the python script then deletes the cookie.file, I don't know if that's exactly what you want, but you can do it by putting a timer in your python script.
You can make a separate thread that keeps track of the time and terminates the code after some time.
An example of such a code could be:
import threading
def eternity(): # your method goes here
while True:
pass
t=threading.Thread(target=eternity) # create a thread running your function
t.start() # let it run using start (not run!)
t.join(3) # join it, with your timeout in seconds
And this code is copied from https://stackoverflow.com/a/30186772/4561068

python script see traceback when running as background

I have a python script running like this on my server:
python script.py &
The script works fine, but constantly I'm adding new things to the script and re-running it, somedays it runs for days without any problem, but sometimes the script stops running (Not running out of memory), but since I started the script as background I have no idea how to check for the Exception or error that cause the script to stop running. I'm on a Ubuntu server box running in Amazon. Any advice on how to approach this inconvenience ?

I use something like this. It will dump the exception which caused termination to your syslog, which you can see by examining /var/log/syslog after your script has stopped.
import traceback
import syslog
def syslog_trace(trace):
'''Log a python stack trace to syslog'''
log_lines = trace.split('\n')
for line in log_lines:
if len(line):
syslog.syslog(line)
def main():
# Your actual program here
if __name__ == '__main__':
try:
main()
except:
syslog_trace(traceback.format_exc())
