Connect to MySQL database using python

Question

So I am having a super hard time connecting to a local database using the python mysql.connector module.

So I am trying to connect using the highlighted connection. I use the password abcdefghijkl to log into the SQL environment. I am trying to connect to a database named flight_school.

My python script looks like so.

import mysql.connector

mydb = mysql.connector.connect("localhost", "root", "abcdefghijkl", "flight_school")

print(mydb.is_connected())

This above code in the arguments in the following order i.e.

hostname = localhost,
user = ‘root’,
password = ‘abcdefghijkl’, and
database name = ‘flight_school’.

It’s just not working. I get the following error.

I would really appreciate some advice, please.

Please read always the official documentation: https://dev.mysql.com/doc/connector-python/en/connector-python-connectargs.html

import mysql.connector
from mysql.connector import errorcode, MySQLConnection

try:
    db_connection = MySQLConnection(user='root', password='', port='3306', database='your_database')
    print("Database connection made!")
except mysql.connector.Error as error:
    if error.errno == errorcode.ER_BAD_DB_ERROR:
        print("Database doesn't exist")
    elif error.errno == errorcode.ER_ACCESS_DENIED_ERROR:
        print("User name or password is wrong")
    else:
        print(error)
else:
    db_connection.close()

cursor = db_connection.cursor()

sql = ("commands")
cursor.execute(sql)
