先入先出、先入后出；按优先级

#!/usr/bin/env python
# Author:Zhangmingda
import  queue

q = queue.Queue() #先入先出
q.put(‘A‘)
q.put(‘B‘)
q.put(‘C‘)
print(q.get())
print(q.get())
print(q.get())

queue先入先出

#!/usr/bin/env python
# Author:Zhangmingda
import  queue

q = queue.LifoQueue() #先入后出
q.put(‘A‘)
q.put(‘B‘)
q.put(‘C‘)
print(q.get())
print(q.get())
print(q.get())

queue先入后出

#!/usr/bin/env python
# Author:Zhangmingda
import  queue

q = queue.PriorityQueue() #优先级策略put内容为元组，第一个为优先级代码，必须全部为数字或者字母
q.put((3,‘zhangsan‘))
q.put((5,‘lisi‘))
q.put((1,‘wangwu‘))
print(q.get())
print(q.get())
print(q.get())

设置优先级数字越小优先级越高
