Python 3.x Python3的Mysql连接器

正在尝试为python3创建数据库类，但进展不太顺利。我拥有的当前代码给出了以下错误：

return self.cursor
[Previous line repeated 995 more times]
RecursionError: maximum recursion depth exceeded

我使用了thread作为参考，但我对使用Mysql/MariaDB更感兴趣。但我认为包装器本身与SQLite应该没有太大区别

这是我的密码

import mysql.connector
from mysql.connector import Error
class Database:
    def __init__(self):
        try:
            connection = mysql.connector.connect(
                        host='localhost',
                        database='db',
                        user='root',
                        # charset='utf8mb4',
                        passwd='')
            if connection.is_connected():
               db_Info = connection.get_server_info()
               print("Connected to MySQL database... MySQL Server version on ",db_Info)
               cursor = connection.cursor(prepared=True)
               cursor.execute("select database();")
               record = cursor.fetchone()
               print ("Your connected to - ", record[0])
        except Error as e :
            print ("Error while connecting to MySQL", e)

    def __enter__(self):
        return self

    def __exit__(self):
        if(connection.is_connected()):
            cursor.commit()
            cursor.close()
            connection.close()
        else:
            print('Something went wrong...')

    @property
    def cursor(self):
        return self.cursor

    def commit(self):
        self.connection.commit()

    def execute(self, sql, params=None):
        self.cursor.execute(sql, params or ())

    def fetchall(self):
        return self.cursor.fetchall()

    def fetchone(self):
        return self.cursor.fetchone()

    def query(self, sql, params=None):
        self.cursor.execute(sql, params or ())
        return self.fetchall()

我还注释掉了

charset=utf8mb4

，因为出现了错误

LookupError:unknown encoding:utf8mb4

，但这是针对另一个线程的
