如何使用另一个脚本重新启动 python 脚本？

Question

('The First script' takes input from the user and 'the second script' notify the task.)

I have been trying to restart a python script using another one but i couldn't succeed it after trying to do a few methods. I developed a reminder, notify user when time previously set by the user has arrived, app works on Linux and it have 2 python script. First one is for taking input that given by the user to schedule a task. For example, "Call the boss at 12:30 pm". Then Linux is going to notify it at 12:30 pm. The other one is checking the inputs and notify them when the time comes.

In first script, i am trying to restart the other script when the user give a new task because the script needs to read the new task to notify it. Also I want to terminate the first script when it ran the second script. But the second script must still be working. In first script, I tried these commands to do that:

os.system(f"pkill -f {path2}")
os.system(f"python {path2}")

These aren't work.

Also I want to run the second script at the startup of my os.

Summary:

1- I wanna restart a python script using another one and the first one should be terminated when the second one is run.

2- I wanna run the second script at the startup of my os.

Repository about my reminder app is here .

Assuming the name of the other script is 2.py (Changeable with the code below), this worked for me pretty well:

1.py:

import subprocess
import os
import time

OTHER_SCRIPT_NAME = "2.py"

process_outputs = subprocess.getoutput("ps aux | grep " + OTHER_SCRIPT_NAME) # Searching for the process running 2.py
wanted_process_info = process_outputs.split("\n")[0] # Getting the first line only
splitted_process_info = wanted_process_info.split(" ") # Splitting the string
splitted_process_info = [x for x in splitted_process_info if x != ''] # Removing empty items
pid = splitted_process_info[1] # PID is the secend item in the ps output
os.system("kill -9 " + str (pid)) # Killing the other process
exit()

time.sleep(1000) # Will not be called because exit() was called before

2.py:

import time

time.sleep(100)

In linux, you can execute scripts on startup by writing it into the /etc/rc.local file

Just run your scripts from the rc.local file and you are good to go:

/etc/rc.local:

python '/path/to/your/scripts'
