一，创建线程

'''''
    功能：输出当前时间
'''
def gettime():
    localtime = time.localtime(time.time())
    year = localtime[0]
    month = localtime[1]
    day = localtime[2]
    hour = localtime[3]
    minute = localtime[4]
    print("本地时间为：" + str(year) + '-' + str(month) + "-" + str(day) + " " + str(hour) + ":" + str(minute))  

#线程类
class testThread(threading.Thread):
    def __init__(self, threadname):
        threading.Thread.__init__(self)
        self.name=threadname  

    def run(self):
        gettime()  

t1 = testThread("test1")
t1.start()
t1.join()  

ps:我用的是python 3.6,之前的版本，可能写法上不是threading这种，是_thread这种。

二，共享数据访问

#!/usr/bin/python3
# -*- coding: utf-8 -*-

import threading
import  time

count = 0
threadLock = threading.Lock()
class AddThread(threading.Thread):
    def __init__(self, threadname):
        threading.Thread.__init__(self)
    def run(self):
        global count
        for i in range(0, 100000):
            threadLock.acquire()
            count = count + 1
            threadLock.release()

t1 = AddThread("t1")
t2 = AddThread("t2")
t1.start()
t2.start()
t1.join()
t2.join()
print (str(count))
