python mysqldb 查询返回字典结构

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') cursor = db.cursor() cursor.execute('select * from user') rs = cursor.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) cursor = db.cursor() cursor.execute('select * from user') rs = cursor.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') cursor = conn.cursor(cursorclass = MySQLdb.cursors.DictCursor) 相关资源:Python MySQLdb 执行sql语句时的参数传递方式
