線程（二）：在first的基礎上對代碼作修改，使得代碼冗餘更少，更靈活

# -*- coding:utf-8 -*-

#以下代碼都是以上一篇爲基礎做整理的，使得代碼更爲簡潔，減少冗餘
#在IDLE編輯器下運行

# 改進第一版
#-------------------------------------------------------------
# import time
# import thread
#
# def loop(nloop,nsec):
#      print("loop%s start at :"%nloop,time.ctime())
#      time.sleep(nsec)
#      print("loop%s stop at :"%nloop,time.ctime())
#
#
# def main():
#     print ('all start at :',time.ctime())
#     sleep_list = [4,2]
#     for i in range(2):
#         thread.start_new_thread(loop,(i,sleep_list[i]))
#     time.sleep(5)
#     print ('all stop at :',time.ctime())
#
# if __name__ =="__main__":
#     main()

#繼續在這之上改進，使得程序更加靈活，第二版
