Nicht elegant, aber es kann die mysteriöse Python-Connector Cursor Klasse entwirren helfen und überträgt die Liste von Tupeln (siehe Copperfield Kommentar) mit den Daten aus der Abfrage in eine Liste (Geräteliste) von Wörterbuch (Einträge) mit Details zu jedem Eintrag in der Datenbank, mit denen in Ihrem Python-Skript einfacher zu arbeiten ist:
# ref: https://dev.mysql.com/doc/connector-python/en/connector-python-api-mysqlcursor.html
import mysql.connector
db = 'test'
table = 'phonebook'
phoneList = []
drop_table = ("DROP TABLE IF EXISTS {};").format(table)
# By default, the starting value for AUTO_INCREMENT is 1, and it will increment by 1 for each new record.
# To let the AUTO_INCREMENT sequence start with another value, use the following SQL statement:
# ALTER TABLE phonebook AUTO_INCREMENT=100;
create_table = ("CREATE TABLE {} ("
"id int NOT NULL AUTO_INCREMENT,"
"name varchar(30) NOT NULL,"
"phone varchar(30) NOT NULL,"
"city varchar(30) NOT NULL,"
"PRIMARY KEY (id))"
" ENGINE=InnoDB DEFAULT CHARSET=latin1;").format(table)
Names = {'Bill':{'phone':'55123123','city':'Melbourne'},
'Mary':{'phone':'77111123','city':'Sydney'},
'Sue':{'phone':'55888123','city':'Melbourne'},
'Harry':{'phone':'77777123','city':'Sydney'},
'Fred':{'phone':'88123444','city':'Yongala'},
'Peter':{'phone':'55999123','city':'Melbourne'}}
cnx = mysql.connector.connect(user='mysqluser', password='xxxx',host='127.0.0.1',database=db)
cursor = cnx.cursor(dictionary=True) # key to using **row format
cursor.execute(drop_table)
cursor.execute(create_table)
# populate db
for name,detail in dict.items(Names):
sql = ("INSERT INTO {} (name,phone,city) VALUES ('{}','{}','{}')".format(table,name,detail['phone'],detail['city']))
cursor.execute(sql)

cursor.execute(sql)
for row in cursor:
print("{id} {name} {phone} {city}".format(**row))
phoneList.append(row)
print phoneList[0]['name'],phoneList[0]['city']

for entries in phoneList:
