Python MYSQL到文本文件-需要标题

import mysql.connector

# 连接到MySQL数据库
cnx = mysql.connector.connect(user='username', password='password',
                              host='localhost', database='database_name')

# 创建游标对象
cursor = cnx.cursor()

# 执行SQL查询
query = "SELECT * FROM table_name"
cursor.execute(query)

# 获取查询结果
results = cursor.fetchall()

# 将结果写入文本文件
with open('output.txt', 'w') as file:
    for row in results:
        file.write(','.join(str(item) for item in row) + '\n')

# 关闭游标和数据库连接
cursor.close()
cnx.close()
