Hello,
You can specify the port of the instance you want to connect to simply by
passing "port=NUM" in MySQLdb.connect(). Here is a formulation I have found
generally useful:
import MySQLdb
def run_mysql(query, db, user, passwd, port=3306,
socket="/var/run/mysqld/mysqld.sock", host="localhost
or an int as it expects for
a keyword argument? Maybe I am missing the use case, so far it just seems
strange to force the keyword to a string.
