심심풀이 땅콩🥜 : 큐(Queue)

큐는 Enqueue와 Dequeue 두가지가 있다. 각 두 코드를 살펴보자.

deque.py

from collections import deque

queue = deque()

queue.append(1)

queue.append(2)

queue.append(3)

first_item = queue.popleft()

second_item = queue.popleft()

print(first_item)

print(second_item)

print(queue)

enque.py

from collections import deque

queue = deque()

queue.append(1)

queue.append(2)

queue.append(3)

first_item = queue.pop()

second_item = queue.pop()

print(first_item)

print(second_item)

print(queue)
