python基础一 ------简单队列用作历史记录

#需求：测试历史记录，一个猜字游戏，能在重新进入游戏时查看输入历史
#

 #-*-coding:utf-8-*-
 from random import randint
 from collections import deque
 import pickle
 guess_num = randint(0,100)

 history = deque([],5)

 while(True):
     num = input("请输入你猜的数字\n")
     if num == "history":

         print(history)
     try:
         num = int(num)
     except:
         print(history)

     history.append(num)

     if num == guess_num:
         print("猜对了")
         break
     elif num<guess_num:
         print("小了")
     elif num>guess_num:
         print("大了")

但是好比浏览器的播放记录，不能无限制查询以往输入。用到队列
