running script multiple times simultaniously in python 2.7

Question

Hello I am trying to run a script multiple times but would like this to take place at the same time from what I understood i was to use subprocess and threading together howev

Answer 1

A little elaboration mgilson's answer:

Let's say we have a folder example1.
Inside example1 we have two python scripts:
execution.py, and main.py

The contents of execution.py looks like this:

import subprocess


def run_main_with_args(filename,name,today,dbfolder):
    print('{} {} {}'.format('\nfilename: ',filename, ''))
    print('{} {} {}'.format('name: ',name, ''))
    print('{} {} {}'.format('today: ',today, ''))
    print('{} {} {}'.format('dbfolder: ',dbfolder, ''))

    outfile = dbfolder+ '/' + name + '.txt'
    with open (outfile, 'w') as fout:
        print('name', file=fout)

Also, the contents of main.py look like this:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#

# Date        : Aug 29, 2016
#

# Imports
import multiprocessing,os,subprocess
import datetime
import execution  # file: execution.py

#assume we have a function:
#exection.run_main_with_args(filename,name,today_str,dbfolder)

today = datetime.datetime.today()
def my_execute(filename):
    if '.txt' in filename:
       name = filename.strip('.txt')
       dbfolder = "db/" + name
       if not os.path.exists(dbfolder): os.makedirs(dbfolder)
       execution.run_main_with_args(filename,name,str(today),dbfolder)



p = multiprocessing.Pool()
p.map(my_execute,['file1.txt', 'file2.txt'])

Then, if we run this main.py it will create required files in the required directories in parallel way!
