Python线程与计时器

Question

我想Python中的3个线程运行n秒。我想同时启动它们并让它们在同一时间完成（毫秒）。我该怎么做呢？

threading.Timer仅在前一个完成后才开始。

Answer 1

import threading 
import time 

class A(threading.Thread): 
    def run(self): 
    print "here", time.time() 
    time.sleep(10) 
    print "there", time.time() 


if __name__=="__main__": 
    for i in range(3): 
    a = A() 
    a.start()
