Python線程與計時器

Question

我想Python中的3個線程運行n秒。我想同時啓動它們並讓它們在同一時間完成（毫秒）。我該怎麼做呢？

threading.Timer僅在前一個完成後纔開始。

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()
