同时运行两个Python 2.7脚本

Question

I have two Python scripts, one of which is try.py which contains this:

import os

os.system('python hello.py')

print "over"

This script calls another script by name hello.py , and hello.py contains:

import time

var = 1

while (var < 60):
    var = var + 1
    print var
    time.sleep(0.5)

There are two problems which I am facing:

• One is I want to run both the scripts simultaneously.

  but in my case my try.py script continues to run after hello.py is finished running.

Answer 1

You might want to use subprocess.Popen() :

import subprocess

p = subprocess.Popen(['python', 'hello.py'])

print "over"
p.wait()
