Python 多线程例子

'''
线程里面的锁
'''
import threading
import time

lock = threading.Lock()  # 创建了锁
share_date = 0  # 创建了一个变量


def tstart():
    time.sleep(0.1)
    global share_date
    if lock.acquire():  # 获取了锁
        share_date += 1
    lock.release()  # 释放锁


# tstart(1)
tlist = list()  # 创建1个list
for i in range(10):
    print(i)
    t = threading.Thread(target=tstart, args='')
    tlist.append(t)
    print(type(t))
print(tlist)  # 10个线程
for t in tlist:
    t.start()

print("this is main:%s" % time.time())
print("this is main:{}".format(time.time()))

for t in tlist:  # 让10个线程都做完
    t.join()

print("结束")
print("现在结果:{}".format(share_date))
