python线程的批量创建

上篇文章介绍了python线程的基础知识和创建的方法，现在开始介线程的批量创建的方法。

在python3 中创建线程有两种方式，一种是通过threading.Thread直接创建线程并运行，一种是通过继承threading.Thread 类来创建线程。

1.用thread.Thread 直接在线程中运行函数

import threading
def worker(name):
    print("thread %s is runing" % name)
worker = threading.Thread(target = worker,args = ('worker',))
worker.start()
worker.join()

运行结果如下：

2.通过继承thread.Thread 来创建线程

import threading
class MyThread(threading.Thread):
    def __init__(self, name):
        threading.Thread.__init__(self)       #这一步是必须的，不加会报错
        self.name = name
    def run(self):
        for i in range(5):
            print("thread %s is runing-----%s" %(self.name,i))
worker1 = MyThread('worker1')
worker2 = MyThread('worker2')

worker1.start()
worker2.start()

worker1.join()
worker2.join()

运行结果如下：

thread worker1 is runing-----0thread worker2 is runing-----0

thread worker1 is runing-----1thread worker2 is runing-----1

thread worker1 is runing-----2thread worker2 is runing-----2

thread worker1 is runing-----3thread worker2 is runing-----3

thread worker1 is runing-----4thread worker2 is runing-----4
