Python 3.4.0 with MySQL database
MySQLdb does not support Python 3 but it is not the only MySQL driver for Python.
mysqlclient is essentially just a fork of MySQLdb with Python 3 support merged in (and a few other improvements).
PyMySQL is a pure python MySQL driver, which means it is slower, but it does not require a compiled C component or MySQL libraries and header files to be installed on client machines. It has Python 3 support.
Another option is simply to use another database system like PostgreSQL.
Use mysql-connector-python. I prefer to install it with pip from PyPI:
pip install --allow-external mysql-connector-python mysql-connector-python
Have a look at its documentation and examples.
If you are going to use pooling make sure your database has enough connections available as the default settings may not be enough.
