从脚本启动不同的脚本

Question

I would like to have several scripts running on PythonAnywhere. In order to make sure that the scripts are not killed I would like to check for their status in an interval of five minutes (based on https://help.pythonanywhere.com/pages/LongRunningTasks/ ).

Two questions arise: 1. In the script which runs every five minutes I would like to check whether the other scripts (script2, script3) are still alive or not. If not, I would obviously like to run them. But how do I run several scripts from one script (script1) without script1 getting "stuck"? Ie how do I start two scripts at the same time from one script?

2. If I just try to run the script using "import script2" I get an error

ImportError: No module named script2

How do I tell Python that the script is in a different folder (because that has to be the issue)?

Thanks in advance!

Try this:

import time
import subprocess 

def check_process(proc,path):    
    if proc.poll()!=1:
        print('%s still running' % proc)
    elif proc.poll()==1:#will give a 1 if the child process has been killed
        print('%s is dead. Re-running')
        subprocess.Popen(['python.exe', path])

script1=subprocess.Popen(['python.exe', pathscript1])
script2=subprocess.Popen(['python.exe', pathscript2])

while True:
    check_process(script1,pathscript1)
    check_process(script2,pathscript2)
    time.sleep(300)
