Accessing MySQL from Python 3: Access denied for user

Question

I tried to access MySQL from Python 3.3 with the following methods:

import mysql.connector

config = {
  \'user\': \'###\',
  \'password\': \'******\',
  \'h         


        

Answer 1

I was having lots of trouble with this same task. Here's what worked for me:

I had to initialize a new database using the legacy password encryption option (compatible with MySQL 5.x):

Once I did that, everything worked fine. I got that suggestion from this article:

And here are some specs:

• I'm using Python 3.7
• I have MySQL 8.0.17 and mysql-connector-python 2.0.4 installed

Answer 2

I was getting this error because I had quotes in my config file.

[mysql]
username: 'uuuu'
password: 'pppp'
host: 'localhost'
database: 'ffffdd'

gave me the error. However, removing the quotes worked:

[mysql]
username: uuuu
password: pppp
host: localhost
database: ffffdd
