  time.sleep(1)

pool = multiprocessing.pool.Pool(processes=10)
pool.map(theout, range(100))

multiprocessing.py

from multiprocessing import Process

  print("Something")

p1 = Process(target=process_file)
p1.start()
p2 = Process(target=process_file)
p2.start()
p1.join()

multithreading.py

import threading
import time

def ThFun(start, stop):
    for item in range(start, stop):
        time.sleep(1)
        print (item)

for n in range(0, i, 10):
    stop = n + 10 if n + 10 <= i else i
    threading.Thread(target = ThFun, args = (n, stop)).start()
