1You need to start different processes (threads aren't enough) so the easiest way is to start them manually.sehigle– sehigle2018-12-20 09:18:32 +00:00Commented Dec 20, 2018 at 9:18

1Welcome to Stackoverfow. You are much more likely to get relevant answers if you can include some code in the question along with a description of what you expect to happen and what actually happens. This site is mostly about helping people to get their existing code working. even if it's a shell script - just let us see what you tried.holdenweb– holdenweb2018-12-20 09:31:19 +00:00Commented Dec 20, 2018 at 9:31

You can easily accomplish this with the subprocess module.
import subprocess
process1 = subprocess.Popen(["python", "pop.py"]) # Create and launch process pop.py using python interpreter
process2 = subprocess.Popen(["python", "pop1.py"])
process3 = subprocess.Popen(["python", "pop2.py"])
process1.wait() # Wait for process1 to finish (basically wait for script to finish)
process2.wait()
process3.wait()

I want to run each file simultaneously
Does it have to be a python solution? With the problem as stated, it might be easiest to just start all three in bash:
python pop.py &
python pop1.py &
python pop2.py &
wait # wait for all three to finish, if needed
While this solution runs them concurrently, you should think about why you want them to be concurrent. Are you trying to parallelize your computation? Are the processes communicating (e.g. a Producer/Consumer pattern)? Are there any dependencies between them? In all but the simplest cases, you would usually be better served by bundling all three python modules together into a python package and adding some runner code which imports all three, starts each as a thread (see oren revenge's answer), and handles any inter-process communication.

I would recommend to read about threading within Python. You should think about rearranging your code in one file.
PSEUDOCODE
import threading
class Pop(threading.Thread):
def run(self):
# Content from "pop.py"
# Maybe some some changes are needed
class Pop1(threading.Thread):
def run(self):
# Content from "pop1.py"
# ...
pop = Pop()
pop1 = Pop1()
# ...
pop.start()
pop1.start()
# ...
Comments
import test1,test2
from threading import Thread
Thread(target=test2.main).start()
Thread(target=test1.main).start()
This script runs test1.py and test2.py concurrently. Hope this helps.

Make main() function in every python file and then import all the files in your main file. Then call all main functions.
from . import pop
from . import pop1
# and so on
# and now call all main functions
pop.main()
pop1.main()
# and so on

See 3 other methods below much better, that also run the .py, not just open !
Method 1: https://gist.github.com/me-suzy/746193a040ae510429c8bcdda73325ab

Most simple method:
Run bebe-ro.bat (change YOUR-USER of your PC)
