python - sqlalchemy: connect to MySQL without password -

i have mysql base "test" no password on root. can log in there

mysql -uroot test # fine

i want access sqlalchemy. try urls:

mysql+mysqldb://root@localhost/test  mysql+mysqldb://root:@localhost/test

but both of them fail error:

sqlalchemy.exc.operationalerror: (operationalerror)     (1045, "access denied user     'root'@'localhost' (using password: no)") none none

how should access base without password?

edit

i tried also:

mysql://root@/test mysql+mysqldb://root@/test

with local dummy account with password, works without problems.

the equivalent sqlalchemy url have on command line is

mysql://root@/test

mysql consideres root user connecting on standard unix socket (no -h in command line client) different user same username connecting via tcp
