python创建属于自己的单词词库 便于背单词

本文实例为大家分享了python创建单词词库的具体代码，供大家参考，具体内容如下

基本思路：以COCA两万单词表为基础，用python爬取金山词霸的单词词性，词义，音频分别存入sqllite。背单词的时候根据需要自定义数据的选择方式。

效果如下：

代码写的比较随意，还请见谅。

创建数据库

代码如下:

cu.execute('create table test (id INTEGER PRIMARY KEY AUTOINCREMENT,dc varchar(20),cx varchar(20),cy varchar(50),mp3 varchar(50));')

完整代码，效率不高，不过够用了

自定义背单词： 根据需要可以将单词放入txt文件中进行测试，可以输出词义拼写单词，也可以输出单词，选择对应释义。 当然还可以给每个单词词义加两个属性值，分别表示学习次数和答错次数，然后可以根据这两个值来选择单词，如果有兴趣的话，可以尝试一下。

import random
import sys
from playsound import playsound
# 中译英
def CtoE():
 for j in list1:

 sql =cu.execute('select id,dc,cx,cy,mp3 from wordinfo where id = ?',(j,))
 for it in sql:
 # 返回的是元组，直接对元组查询
 c=0
 while c<3:
 print("当前单词ID = "+str(it[0]))
 print("释义："+it[3])
 # 播放音频
 playsound(it[4])
 a = input("请拼写单词,共有三次机会:")
 if a == it[1]:
 print("拼写正确")
 break;
 c += 1
 print('第%d次拼写错误'%c)
 print('\n')
 print("下一个")
 print('\n')
# 英译中
def EtoC():
 for j in list1:
 sql =cu.execute('select id,dc,cx,cy,mp3 from wordinfo where id = ?',(j,))
 d =0
 for it in sql:
 # 返回的是元组，直接对元组查询

 while c<3:
 # 释放list2
 list2 = []

 for t in sql:
 for o in range(len(t)):
 #将随机取出的数据放入列表
 list2.append(t[o])
 # 加入正确答案
 p = random.randint(0,3)
 list2.insert(p,it[3])
 print("当前单词ID = "+str(it[0]))
 print("选择单词的对应释义：----"+it[1])
