如何将类中的mySQL结果传递给外部函数？

import mysql.connector

class MySQLConnector:
    def __init__(self):
        self.connection = mysql.connector.connect(
            host="localhost",
            user="username",
            password="password",
            database="database_name"
        )
        self.cursor = self.connection.cursor()
        self.result = None

    def execute_query(self, query):
        self.cursor.execute(query)
        self.result = self.cursor.fetchall()

    def get_result(self):
        return self.result

# 外部函数
def process_mysql_result():
    mysql_connector = MySQLConnector()
    mysql_connector.execute_query("SELECT * FROM table_name")
    result = mysql_connector.get_result()
    # 在这里可以对结果进行进一步处理或使用

# 调用外部函数
process_mysql_result()
