Python thread

第一种thread：定义threading的target，目标运行函数

import threading

def worker():
    """thread worker function"""
    print 'Worker'
    return

threads = []
for i in range(5):
    t = threading.Thread(target=worker)
    threads.append(t)
    t.start()

Worker
Worker
Worker
Worker
Worker

第二种thread 定义自己的run函数

import threading
import logging

logging.basicConfig(level=logging.DEBUG,
                    format='(%(threadName)-10s) %(message)s',
                    )

class MyThread(threading.Thread):

    def run(self):
        logging.debug('running')
        return

for i in range(5):
    t = MyThread()
    t.start()

(Thread-1  ) running
(Thread-2  ) running
(Thread-3  ) running
(Thread-4  ) running
(Thread-5  ) running
