print "Number of rows returned: %d" % cursor.rowcount
cursor.close()

##  fetchall() 行序列方式返回整个结果集
cursor = conn.cursor()
cursor.execute("SELECT id, name, cats FROM profile")
rows= cursor.fetchall() #len(rows) 
for row in rows:  #rows[1][2]
    print "id: %s, name: %s, cats:%s" % (row[0],row[1],row[2])
print "Number of rows returned: %d" % cursor.rowcount
cursor.close()


##  DictCursor通过列名来访问行值
cursor = conn.cursor(MySQLdb.cursor.DictCursor)
cursor.execute("SELECT id, name, cats FROM profile")
for row in cursor.fetchall():
    print "id: %s, name: %s, cats:%s" % (row[0],row[1],row[2])
print "Number of rows returned: %d" % cursor.rowcount
cursor.close()

OSX mysql cannot load

mysql> use mysql;
ERROR 1044 (42000): Access denied for user ''@'localhost' to database ‘mysql'

Then I do with this:

sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop
sudo /usr/local/mysql/bin//mysqld_safe --skip-grant-table
# start a new term
mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root’;
mysql> FLUSH PRIVILEGES;
mysql> \q
