python AttributeError: ‘MysqlDb‘ object has no attribute ‘cur‘

代码一直报错一直执行不了，看了好久代码，根据报错的信息看了很久 ，一直没看出有什么问题

Traceback (most recent call last):
  File "C:UsersAdministratorPycharmProjectspythonProjectutildb_util.py", line 16, in
    r = mydb.query("select * from `case`")
  File "C:UsersAdministratorPycharmProjectspythonProjectutildb_util.py", line 10, in query
    self.cur.execute(sql)
AttributeError: 'MysqlDb' object has no attribute 'cur'

import pymysql

class MysqlDb:

    def __int__(self):
        self.conn = pymysql.connect(host="192.168.253.128", user="root", password="123456", database="testcase")
        self.cur = self.conn.cursor(cursor=pymysql.cursors.DictCursor)

    def query(self,sql):
        self.cur.execute(sql)
        data = self.cur.fetchall()
        return data

if __name__ == '__main__':
    mydb = MysqlDb()
    r = mydb.query("select * from `case`")
    #r = mydb.execute("insert into `case` (`app`) values('xd')")
    print(r)

通过代码对比发现是打__init__的时候，莫名其妙带出的是 __int__，卧槽，真的无语死了，关键是报错信息也不对！

快捷代码在带出的时候还是要看清楚了，python报错给出的提示的信息不一定是准确的。
