import queue
#創(chuàng)建基本隊(duì)列
#queue.Queue(maxsize=0)創(chuàng)建一個(gè)隊(duì)列對(duì)象（隊(duì)列容量），若maxsize小于或者等于0，隊(duì)列大小沒有限制
Q=queue.Queue(10)
print(Q)
print(type(Q))
#1.基本方法
print(Q.queue)#查看隊(duì)列中所有元素
print(Q.qsize())#返回隊(duì)列的大小
print(Q.empty())#判斷隊(duì)空
print(Q.full())#判斷隊(duì)滿
#2.獲取隊(duì)列，0--5
#Queue.put（item，block = True，timeout = None ）將對(duì)象放入隊(duì)列，阻塞調(diào)用（block=False拋異常），無等待時(shí)間
for i in range(5):
    Q.put(i)
# Queue.put_nowait(item)相當(dāng)于 put(item, False).
#3.讀隊(duì)列，0--5
#Queue.get(block=True, timeout=None)讀出隊(duì)列的一個(gè)元素，阻塞調(diào)用，無等待時(shí)間
while not Q.empty():
    print(Q.get())
# Queue.get_nowait()相當(dāng)于get(False).取數(shù)據(jù)，如果沒數(shù)據(jù)拋queue.Empty異常
#4.另兩種涉及等待排隊(duì)任務(wù)的方法
# Queue.task_done()在完成一項(xiàng)工作后，向任務(wù)已經(jīng)完成的隊(duì)列發(fā)送一個(gè)信號(hào)
# Queue.join()阻止直到隊(duì)列中的所有項(xiàng)目都被獲取并處理。即等到隊(duì)列為空再執(zhí)行別的操作
