MySQLdb默认查询结果都是返回tuple,输出时候不是很方便,必须按照0,1这样读取,无意中在网上找到简单的修改方法,就是传递一个cursors.DictCursor就行。

默认程序:

import MySQLdb
db  = MySQLdb.connect(host='localhost', user='root', passwd='123456', db='test')
cur = db.cursor()
cur.execute('select * from user')
rs = cur.fetchall()
print rs
# 返回类似如下
# ((1000L, 0L), (2000L, 0L), (3000L, 0L))

修改后:

import MySQLdb
import MySQLdb.cursors
db = MySQLdb.connect(host='localhost', user='root', passwd='123456', db='test',
                     cursorclass=MySQLdb.cursors.DictCursor)
cur = db.cursor()
cur.execute('select * from user')
rs = cur.fetchall()
print rs
# 返回类似如下
# ({'age': 0L, 'num': 1000L}, {'age': 0L, 'num': 2000L}, {'age': 0L, 'num': 3000L})

或者也可以用下面替换connect和cursor部分

db  = MySQLdb.connect(host='localhost', user='root', passwd='123456', db='test')
cur = db.cursor(cursorclass=MySQLdb.cursors.DictCursor)
