threading.local

import threading
import time


def music(a,b):
   fo = open("test.txt1", "w")
    fo.write(a+b)
    fo.close()

def move(c,d):
   fo = open("test.txt2", "w")
    fo.write(c+d)
    fo.close()

# 关闭文件
fo.close()

threads = []
t1 = threading.Thread(target=music,args=("aa","bb"),name="aaaaaa")
threads.append(t1)
t2 = threading.Thread(target=move,args=("cc","dd"),name="bbbbbb")
threads.append(t2)

if __name__ == '__main__':
    for t in threads:
        t.setDaemon(False)
        t.start()

    print "all over"

Python提供了 threading.local 类，将这个类实例化得到一个全局对象，

但是不同的线程使用这个对象存储的数据其它线程不可见(本质上就是不同的线程使用这个对象时为其创建一个独立的字典)。
