Python多线程简单例子

直接附上代码：

#!/usr/bin/python
# coding:utf-8
import threading
import time


class Test(threading.Thread):
def __init__(self):
        threading.Thread.__init__(self)
# self._run_num = num

def run(self):
global count, mutex
        threadname = threading.currentThread().getName()

# for x in xrange(0, int(self._run_num)):
        mutex.acquire()
        count += 1
        mutex.release()
print '线程信息名字：', threadname
print '在这个线程中的编号： ', x
print '累计和： ', count
# time.sleep(1)


global count, mutex
threads = []
num = 4
count = 0
mutex = threading.Lock()

for x in xrange(0, num):
    threads.append(Test())

for t in threads:
    t.start()

for t in threads:
    t.join()
