今天做一個背單詞（程序員）的小遊戲，用到了redis來儲存單詞

今天其實是用來複習redis的，結果存儲單詞只用到了hash類型

數據來源
這個小遊戲的思路：
一. 先把單詞信息存在redis中（以hash類型）

1. 從網上爬取單詞文本信息
2. 讀取文本信息並將單詞和詞語分離
3. 單詞和詞義分別作爲鍵和值存進redis中（field和value）

from redis import *
#	鏈接Redis
sr = StrictRedis(host="localhost", port=6379, db=0)
# html.text是爬取到的單詞信息
with open("html.text",'r') as f:
    t = f.readlines()
# 判斷是否是中文，ord()返回字符的ascii碼
def ord_num(word):
    return ord(word)<127

num = 1
for i in t:
    n = 0
    for j in i:
        if ord_num(j):
            n += 1
        else:
            break
    key = i[0:n-1]
    value = i[n:]
    sr.hset(str(num),key, value)
    num += 1

二.完成信息存儲後，開始編寫遊戲

1. 鏈接redis服務器：

from redis import *
import random
sr = StrictRedis(host="localhost", port=6379, db=0)

2. 在1~705中隨機生成四個數並轉換成字符類型（方便用redis索引）：

index = [str(random.randint(1,705)) for i in range(4)]

3. 根據隨機生成的字符向redis獲取信息：

for i in index:
	word = {}
	word['key'] = str(sr.hkeys(i)[0], encoding="utf-8")
	word['value'] = sr.hvals(i)[0].decode().replace("\n","")
	words.append(word)

4. 生成選擇信息：

print("詞組“{}”的意思是：".format(words[0]["key"]))
ges_list = [0,1,2,3]
random.shuffle(ges_list)
print("a.{} b.{} c.{} d.{}".format(words[ges_list[0]]['value'],
                                   words[ges_list[1]]['value'],
                                   words[ges_list[2]]['value'],
                                   words[ges_list[3]]['value']))

5. 判斷選擇：

ges = input("選擇：")
    if ges not in ans:
        print("請選擇a、b、c、d")
        print()
        continue
    if ges_list[pr[ges]] == 0:
        print("選擇正確")
    else:
        print("錯。正確答案是{}".format(ans[ges_list.index(0)]))
    print()

6. 最後對代碼添加循環就完成小遊戲啦：

from redis import *
import random
sr = StrictRedis(host="localhost", port=6379, db=0)

pr = {i:j for i,j in zip(['a','b','c','d'],[0,1,2,3])}
ans = ['a','b','c','d']
while True:
    index = [str(random.randint(1,705)) for i in range(4)]
    words = []
    for i in index:
        word = {}
        word['key'] = str(sr.hkeys(i)[0], encoding="utf-8")
        word['value'] = sr.hvals(i)[0].decode().replace("\n","")
        words.append(word)
    print("詞組“{}”的意思是：".format(words[0]["key"]))
    ges_list = [0,1,2,3]
    random.shuffle(ges_list)
    print("a.{} b.{} c.{} d.{}".format(words[ges_list[0]]['value'],
                                       words[ges_list[1]]['value'],
                                       words[ges_list[2]]['value'],
                                       words[ges_list[3]]['value']))

    ges = input("選擇：")
    if ges not in ans:
        print("請選擇a、b、c、d")
        print()
        continue
    if ges_list[pr[ges]] == 0:
        print("選擇正確")
    else:
        print("錯。正確答案是{}".format(ans[ges_list.index(0)]))
    print()
