Python使用面向对象方式创建线程实现12306售票系统

import threading # Python主要通过标准库中的threading包来实现多线程
import time
import os
#作为间隔 每次调用间隔.s
def doChore():
time.sleep(.)
# 定义一个类BoothThread继承自thread.Threading类
class BoothThread(threading.Thread):
def __init__(self, tid, monitor):
self.tid = tid
self.monitor = monitor
threading.Thread.__init__(self)
def run(self):
while True:
monitor['lock'].acquire() # 调用lock.acquire() 加锁
if monitor['tick'] != :
monitor['tick'] = monitor['tick'] - # 售票 售出一张减少一张
print(self.tid,':now left:',monitor['tick']) # 剩下的票数
doChore() 
else:
print("Thread_id",self.tid," No more tickets")
os._exit() # 票售完 退出程序
monitor['lock'].release() # 释放锁
doChore() 
monitor = {'tick':, 'lock':threading.Lock()} # 初始化票数
# 总共设置了个线程
for k in range():
new_thread = BoothThread(k, monitor) # 创建线程; Python使用threading.Thread对象来代表线程 类BoothThread继承自thread.Threading类 
new_thread.start() # 调用start()方法启动线程
