mysql.connector.errors.ProgrammingError: 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

This error message indicates that the user 'root' is being denied access to the MySQL database on the localhost server, likely due to an incorrect password being entered.

To resolve this issue, you can try the following steps:

1. Double-check the password for the 'root' user to ensure it is correct.
2. Verify that the 'root' user has the necessary privileges to access the database.
3. Check the MySQL server logs for any relevant error messages that may provide additional information about the cause of the issue.
4. Try resetting the password for the 'root' user or creating a new user with appropriate privileges.

If none of these steps resolve the issue, it may be necessary to seek further assistance from a MySQL database administrator or support team.
