多线程threading模块例子

import threading
import time

flag = True
def fun01():
    global flag
    time.sleep(5)
    flag = False if flag else True
    print("flag:" + str(flag))

def fun02():
    begin_time = time.time()
    wait_time = 6
    while 1:
        if time.time() - begin_time > wait_time:
            raise Exception("Time out")
        elif not flag:
            print("Start")
            break
        else:
            continue
t1 = threading.Thread(target=fun01)
t2 = threading.Thread(target=fun02)
t1.start()
t2.start()
