“Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)”)

I am using mysqldb (the python MySQL) module.. But everytime I try to run. it gives me this error.

   super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through     socket '/var/run/mysqld/mysqld.sock' (2)")

I think the issue is multiple mysql installed.. but I am no mysql expert.. actually besides python.. assume i have a very minimal knowledge of OS.. mysql.or any other thing, :)

I have also installed XAMPP on ubuntu.. and everytime i start the xampp module But before I start the xampp server.. I always do the following..

sudo /etc/init.d/mysql stop (this is my clue that there is another mysql installed :D )

To start the XAMPP local host I do the following

sudo /opt/lampp/lampp start

And the error says

_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")

I am elaborating on all of the above just to demonstrate where the paths of what is relevant to solve this thing lives.. Can you please help me out. Thanks.
