You try the following ways to run the multiple python scripts     import os   print  Starting script1    os system  python script1 py arg1 arg2 arg3     print  script1 ended    print  Starting script2    os system  python script2 py arg1 arg2 arg3     print  script2 ended    Note  The execution of multiple scripts depends purely underlined operating system  and it won t be concurrent  I was new comer in Python when I answered it    Update  I found a package  https   pypi org project schedule   Above package can be used to run multiple scripts and function  please check this and maybe on weekend will provide some example too   i e    import schedule  import time  import script1  script2   def job         print  I m working        schedule every 10  minutes do job   schedule every   hour do job   schedule every   day at  10 30   do job   schedule every 5  to 10  days do job   schedule every   monday do job   schedule every   wednesday at  13 15   do job    while True       schedule run pending        time sleep 1

With Bash     python script1 py  amp  python script2 py  amp    That s the entire script  It will run the two Python scripts at the same time   Python could do the same thing itself but it would take a lot more typing and is a bad choice for the problem at hand   I think it s possible though that you are taking the wrong approach to solving your problem  and I d like to hear what you re getting at

I do this in node js  on Windows 10  by opening 2 separate cmd instances and running each program in each instance   This has the advantage that writing to the console is easily visible for each script   I see that in python can do the same  2 shells           You can run multiple instances of IDLE Python shell at the same time  So open IDLE and run the server code and then open up IDLE again  which will start a separate instance and then run your client code

The simplest solution to run two Python processes concurrently is to run them from a bash file  and tell each process to go into the background with the  amp  shell operator   python script1 py  amp  python script2 py  amp    For a more controlled way to run many processes in parallel  look into the Supervisor project  or use the multiprocessing module to orchestrate from inside Python
