python MySQLdb error?

while i am trying to connect with python MySQLdb, i get an 'Invalid Arguments' error.

import MySQLdb
conn = MySQLdb.connect (host = "localhost",user = "root",passwd = "",db = "test")

what is the reason for getting such a error?.

But, the following code with _mysql works fi开发者_开发技巧ne.

db=_mysql.connect("localhost","root","","test")

import MySQLdb.cursors

DATABASE= MySQLdb.connect(host='localhost', user='username', passwd='password', db='databasename', cursorclass=MySQLdb.cursors.DictCursor)

Hope it helps.

Shouldn't that be

conn = MySQLdb.connect ("localhost","root","","test")

?
