如何创建一个for循环来选择表中的列，从而生成单独的数据文件？

import mysql.connector
import csv

# 连接到数据库
conn = mysql.connector.connect(
    host="localhost",
    user="your_username",
    password="your_password",
    database="your_database"
)

# 查询表结构
cursor = conn.cursor()
cursor.execute("DESCRIBE your_table")
table_structure = cursor.fetchall()

# 创建for循环
for column in table_structure:
    column_name = column[0]

    # 选择列并生成数据文件
    cursor.execute(f"SELECT {column_name} FROM your_table")
    data = cursor.fetchall()

    with open(f"{column_name}.csv", "w", newline="") as file:
        writer = csv.writer(file)
        writer.writerows(data)

# 关闭数据库连接
cursor.close()
conn.close()
