Python 多线程中使用各自独立的变量

最简单的思路是每个 线程都使用各自私有的变量，但是python提供了一种更佳的解决方案

threading.local 线程中使用各自独立的局部变量
'''
import threading
import random, time

class ThreadLocal():
    def __init__(self):
        self.local = threading.local()
    def run(self):
        time.sleep(random.random())
        self.local.number =[]
        for i in range (10):
            self.local.number.append(random.choice(range(10)))
        print threading.currentThread(), self.local.number

threadLocal = ThreadLocal()
threads = []
for i in range(5):
    t = threading.Thread(target=threadLocal.run)
    t.start()
    threads.append(t)
for i in range(5):
    threads[i].join

console:

 [4, 0, 1, 8, 0, 6, 3, 1, 1, 3]
 [5, 5, 4, 0, 5, 7, 8, 6, 0, 7]
 [7, 6, 6, 8, 8, 3, 1, 2, 8, 4]
 [4, 0, 1, 2, 3, 1, 3, 2, 5, 1]
 [5, 6, 6, 9, 2, 4, 1, 9, 5, 7]
