mysql-connector-python for python3 installed - where? (no replies)

I run Linux Mint 18.3 based on Ubuntu16.04.1. I have started to use python3.6 which I installed (python 2.7 & 3.5 obviousli came with the distro Mint 18.3)
I have (via the community page) tried to install mysql-connector-python-cext-py3
The installer displays some directories which I guess are relevant directories from where to import mysql connector.
But none of these directories seem to contain the names that I suppose must be imported into the python script to connect to the database.
I have from the installer:
1)usr/lib/python3/dist-packages/_mysql_connector.cpython-35m-i386-linux-gnu-so.
2)usr/share/dic/mysql-connector-python-cext-py3/
I also have in my file system
3)usr/lib/python3/dist packages/mysql/connector
in 3) there is no .py module called connector, only one called connection.py.

Trying this:
#!/usr/lib/python3/disp-packages/mysql/connection
from __future__ import print_function

import mysql.connection
from mysql.connection import errorcode

Results in failure.
Traceback (most recent call last):
File "testsql.py", line 4, in <module>
import mysql.connection
ModuleNotFoundError: No module named 'mysql'

So, this construct requires a mysql mdule , byt I do not know where it can be found. Something may have gone wrong during installation.
Can you give me the necessary hints?
