队列实现

1 python队列实现,使用队列的时候要用collections来实现,这样更方便,因为它有类似list的用法,而用deque模块实现的队列用的是get,put方法,

# python3里面用queue模块
from queue import Queue
q = Queue()
q.put(3)
q.put(7)
print(q.get()) # 3
print(q.get()) # 7

# 双端队列
from collections import deque
d = deque()
d.append(2)
d.append(3)
print(d)
print(len(d))
print(d.pop())
print(d.popleft())
# deque([2, 3])
# 2
# 3
# 2
