if you want to use MySQLdb first you have to install pymysql on your pc by typing in cmd of windows

    pip install pymysql

then in python shell, type

    import pymysql
    pymysql.install_as_MySQLdb()
    import MySQLdb
    db = MySQLdb.connect("localhost" , "root" , "password")

this will establish the connection.

This does not fully answer my original question  but I think it is important to let everyone know what I did and why     I chose to continue using python 2 7 instead of python 3 because of the prevalence of 2 7 examples and modules on the web in general   I now use both mysqldb and mysql connector to connect to MySQL in Python 2 7   Both are great and work well   I think mysql connector is ultimately better long term however

I also tried using pymysql  on my Win7 x64 machine  Python 3 3   without too much luck  I downloaded the  tar gz  extract  ran  setup py install   and everything seemed fine  Until I tried connecting to a database  and got  KeyError  56    An error which I was unable to find documented anywhere   So I gave up on pymysql  and I settled on the Oracle MySQL connector   It comes as a setup package  and works out of the box  And it also seems decently documented

PyMySQL gives MySQLDb like interface as well  You could try in your initialization   import pymysql pymysql install as MySQLdb     Also there is a port of mysql-python on github for python3   https   github com davispuh MySQL-for-Python-3

I m using cymysql with python3 on a raspberry pi I simply installed by  sudo pip3 install cython sudo pip3 install cymysql where cython is not necessary but should make cymysql faster  So far it works like a charm and very similar to MySQLdb

Summary     Mysqlclient is the best alternative IMHO  because it works flawlessly with   Python 3   follows expected conventions  unlike mysql   connector   uses the object name mysqldb which enables convenient porting of    existing software and is used by Django for Python 3 builds   Is there a repository available where the binaries exist for mysqldb       Yes   mysqlclient allows you to use mysqldb functions   Though    remember this is not a direct port by mysqldb  but a build by mysqlclient   How can I connect to MySQL in Python 3 on Windows      pip install mysqlclient   Example      Python36 python  Please change above path to suit your platform   Am running it on Windows import MySQLdb db   MySQLdb connect user  my-username  passwd  my-password  host  localhost  db  my-databasename   cursor   db cursor   cursor execute  SELECT   from my-table-name   data cursor fetchall   for row in data       print  row  db close     I can t find mysqldb for Python 3      mysqldb has not been ported yet

You should probably use pymysql - Pure Python MySQL client instead  It works with Python 3 x  and doesn t have any dependencies   This pure Python MySQL client provides a DB-API to a MySQL database by talking directly to the server via the binary client server protocol  Example  import pymysql conn   pymysql connect host  127 0 0 1   unix socket   tmp mysql sock   user  root   passwd None  db  mysql   cur   conn cursor   cur execute  quot SELECT Host User FROM user quot   for r in cur      print r  cur close   conn close

There are currently a few options for using Python 3 with mysql   https   pypi python org pypi mysql-connector-python   Officially supported by Oracle Pure python A little slow Not compatible with MySQLdb   https   pypi python org pypi pymysql   Pure python Faster than mysql-connector Almost completely compatible with MySQLdb  after calling pymysql install as MySQLdb     https   pypi python org pypi cymysql   fork of pymysql with optional C speedups   https   pypi python org pypi mysqlclient   Django s recommended library  Friendly fork of the original MySQLdb  hopes to merge back some day The fastest implementation  as it is C based  The most compatible with MySQLdb  as it is a fork Debian and Ubuntu use it to provide both python-mysqldb andpython3-mysqldb packages    benchmarks here  https   github com methane mysql-driver-benchmarks
