How to perform a function several times simultaneously?

What my code does:

import time

def oi():
    while True:
        print("oi")
        time.sleep(1)

oi()

Output (in 2 seconds past):

oi
oi

What I want you to do:

import time
import multiprocessing

def oi():
    while True:
        print("oi")
        time.sleep(1)

quantidadeDeProcessos = 3

multiprocess(quantidadeDeProcessos, oi())

Output (in 2 seconds past):

oi
oi
oi
oi
oi
oi

Is there any way to do that?

    Is there any relation of this question to the How to speed up my python program? If yes, would use this to make HTTP calls in parallel?

  • No, I was just wondering if it’s possible to do that

One way to do this is simply by multiplying the amount of "hi’s" by the number of processes:

from time import sleep

def oi(num_process):
    while True:
        print('oi\n' * num_process)
        sleep(1)

oi(3)

The output will look like this (in 2 seconds interval):

oi
oi
oi

oi
oi
oi

  • but this function that I said was just an example, wanted a mode that works with any kind of function

  • @x8ss, but this would work with any type of typed string. What do you really want? Examples best your question :)

I figured out a way using the threading module:

import threading
import time

def a():
    while True:
        print("oi")
        time.sleep(1)

numeroDeProcessos = 3

if __name__ == "__main__":
    for i in range(numeroDeProcessos):
        threading.Thread(target=a).start()
