无法在jupyter notebook中使用mysql.connector 8.0执行语法正确的查询

!pip install mysql-connector-python

import mysql.connector

# 建立与MySQL数据库的连接
cnx = mysql.connector.connect(
    host="localhost",
    user="your_username",
    password="your_password",
    database="your_database"
)

# 执行查询语句
cursor = cnx.cursor()
query = "SELECT * FROM your_table"
cursor.execute(query)

# 获取查询结果
result = cursor.fetchall()

# 关闭连接
cursor.close()
cnx.close()

import mysql.connector
print(mysql.connector.__version__)
