AttributeError: module 'mysql' has no attribute 'connector'

I'm running Ubuntu 16.04, trying to connect to mysql in python:

    import mysql
    username = 'root'

    cnx = mysql.connector.connect(user=username, database='db')
    cnx.close()

But I get an error:

    File "pysql1.py", line 4, in <module>
      cnx = mysql.connector.connect(user=username, database='db')
    AttributeError: module 'mysql' has no attribute 'connector'

I installed the mysql python module by downloading the package here. I tried sudo apt-get install python-mysql.connector to no avail. Any pointers?

EDIT: after adding import mysql.connector I got an unrelated permissions error which I've now resolved, so that's what I needed ty lots!!!

The solution is to execute :

import mysql.connector # or from mysql import connector

Because the module connector is only available when you import it explicitly :

import mysql

print(dir(mysql))
>>> ['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', 
'__package__', '__path__', '__spec__']

import mysql.connector

print(dir(mysql))
>>> ['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', 
'__package__', '__path__', '__spec__', 'connector']

The __init__ file in the module mysql doesn't import the module connector.

mysql
|_______ __init__.py # no import at this level
|_______ connector
         |________ __init__.py

This could work implicitly if connector was imported inside __init__ with : from . import connector.
