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()
