def __init__(self, host='', user='', password='', database=''):
    self.__host     = 'localhost'
    self.__user     = 'root'
    self.__password = 'mypass'
    self.__database = 'drive'
## End def __init__

def __open(self):
    try:
cnx = MySQLdb.connect(self.__host, self.__user, self.__password, self.__database, port="3308")
self.__connection = cnx
self.__session    = cnx.cursor()

except MySQLdb.Error as e: print "\\033[31mError %d: %s\\033[0m" % (e.args[0],e.args 1 )

I read this question and this one but i have already the same eror and i can' access to my database

Answer 1

Check if you are correctly setting the root password, but remember you can reset the password.

First things first.

Stop mysql server

sudo /etc/init.d/mysql stop

Log in as root and stop the mysql daemon. Now lets start up the mysql daemon and skip the grant tables which store the passwords.

mysqld_safe --skip-grant-tables &

You should see mysqld start up successfully. If not, well you have bigger issues. Now you should be able to connect to mysql without a password.

mysql -u root mysql

update user set Password=PASSWORD('new-password') where user='root';
flush privileges;

exit;

Answer 2

had same issue ,changed connector and it worked for me, but first install the module

$ pip install mysql-connector-python

import mysql.connector
cnx = mysql.connector.connect(user='root', password='psw', host='127.0.0.1', database='db')

Answer 3

尝试在末尾添加Grant Option：

GRANT all privileges on dbx.* to 'x'@'localhost' IDENTIFIED BY 'x' WITH GRANT OPTION;
