#需求：測試歷史記錄，一個猜字遊戲，能在重新進入遊戲時查看輸入歷史
#

 1 #-*-coding:utf-8-*-
 2 from random import randint
 3 from collections import deque
 4 import pickle
 5 guess_num = randint(0,100)
 6 
 7 history = deque([],5)
 8 
 9 while(True):
10     num = input("請輸入你猜的數字\n")
11     if num == "history":
12         
13         print
 
(history)
14     try:
15         num = int(num)
16     except:
17         print(history)
18 
19     history.append(num)
20 
21 
22     if num == guess_num:
23         print("猜對了")
24         break
25     elif num<guess_num:
26         print("小了")
27     elif num>guess_num:
28         print("大了"
 
)
29 
30         

但是好比瀏覽器的播放記錄，不能無限制查詢以往輸入。用到隊列

python基礎一 ------簡單隊列用作歷史記錄
