如何在使用Python调用SQL时允许未定义数量的多个变量

import mysql.connector

def execute_query(query, params):
    conn = mysql.connector.connect(
        host='localhost',
        user='username',
        password='password',
        database='database_name'
    )
    cursor = conn.cursor()
    cursor.execute(query, params)
    result = cursor.fetchall()
    conn.close()
    return result

# 示例查询语句
query = "SELECT * FROM table_name WHERE column1 = %s AND column2 = %s"

# 示例变量值
params = ('value1', 'value2')

# 调用execute_query函数执行查询
result = execute_query(query, params)

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