Using Mysql with Python in Ubuntu

I tried to install MysqlDb package on the ubuntu machine. After download the source code package, I try to use "python setup.py build" to install.
But... It told me that the mysql_config could not be found. Ok, then I tried to install mysql_config.
It is not as easy as I thought... I don't know how to install it...
Finally, I found out that mysql_config is hidden under the libmysqlclient15-dev package...
