如何用python从点文件中生成sql查询？

import mysql.connector

# 读取点文件
with open('points.txt', 'r') as file:
    lines = file.readlines()

# 解析点文件并生成SQL查询语句
sql_query = "SELECT * FROM points WHERE "
for line in lines:
    x, y = line.strip().split(',')
    sql_query += f"(x = {x} AND y = {y}) OR "

# 去除最后一个多余的OR
sql_query = sql_query[:-4]

# 连接到数据库并执行SQL查询
cnx = mysql.connector.connect(user='username', password='password', host='localhost', database='database')
cursor = cnx.cursor()
cursor.execute(sql_query)

# 处理查询结果
for result in cursor:
    print(result)

# 关闭数据库连接
cursor.close()
cnx.close()
