多线程—卖票
题目：python3多线程
import threading import time list_ticket=[] #定义票池 lock=threading.Lock() #获得多线程锁 num=30#票数 for i in range(1,num+1): #ticket_num="0"*(len(str(num))-len(str(i)))+str(i) #001,003,013 ticket_num=str(i).zfill(3) list_ticket.append(ticket_num) # print(list_ticket) def seel_ticket(num): # 通过传参来用窗口买票 #全局变量 # global list_ticket #time.sleep(1) while len(list_ticket)>0: #time.sleep(0.5) lock.acquire() #打开线程锁 print("正在打印票") thre = list_ticket[0] #依次买票 print(num,"号窗口售票点出票成功，票号为:",thre ) del list_ticket[0] #取出以后就得马上删除 lock.release() #释放 time.sleep(0.1) # 必须有这个睡眠 #++++++=========================================================== # #新建线程 # list_thread=[] # 线程的集合 for i in range(5): thread = threading.Thread(target=seel_ticket, args=(i+1,)).start() # list_thread.append(thread) # for i in list_thread: # i.start() # #创建5个线程 # thread=threading.Thread(target=seel_ticket,args=(1,)) # thread2=threading.Thread(target=seel_ticket,args=(2,)) # thread3=threading.Thread(target=seel_ticket,args=(3,)) # thread4=threading.Thread(target=seel_ticket,args=(4,)) # thread5=threading.Thread(target=seel_ticket,args=(5,)) # #启动 # thread.start() # thread2.start() # thread3.start() # thread4.start() # thread5.start()
