如何在 python 中使用 os.system() 同时执行多个命令

Question

import os  
import sys

command_0 = './main'
command_1 = './main'

os.system(command_0)
os.system(command_1)

I want to run a script called 'main' twice simultaneously using python, the problem is that command_0 run for 5 seconds and only when it finishes the command_1 is called. Is it possible to run both simultaneously?

Answer 1

you have 2 options:

1. add & to the command so it will run in the background

os.system(command &)

2. use queue / subprocess:

    def worker(): while True: item = q.get() os.system(item) q = Queue() for i in tasks: t = Thread(target=worker) t.setDaemon(True) t.start() for item in tasks: q.put(item) q.join()
