python mysql全文搜索打印类似的单词

Question

我有一个文本文件＆＃39; hi.txt＆＃39;它有：

i have a friendy whosr name is winy.And has  a friend who is greatly.

我有一个数据库表testtb

testid test1
1      hello
2      hi
3      friend
4      great
5      win

我想将输出打印为：

friendy
winy
greatly

我想使用全文索引打印所有行的相似单词。它不仅用于给定示例，所以不要单独限制此示例。请回答！

我创建了一个程序：

import MySQLdb
db = MySQLdb.connect(host="localhost", # your host, usually localhost
                     user="root", # your username
                      passwd="mysql", # your password
                      db="sakila")


with open('qwer2.txt','r') as file, db as cursor:
    for line in file:
        query=SELECT * FROM testtb WHERE MATCH (test1) AGAINST (line)

        if key in keywords:
            print key

cursor.execute(query)

它没有产生任何输出，所以请帮助！答案将不胜感激。
