python学习之 －mysql 连接和db_config配置

最近学习python,记录下自己写学习python的代码和心得,自己写了一个使用python mysql 的查询语句和做的一个db_config.py 配置信息。

1、db_config.py 配置文件

 #/usr/bin/python

 class mysql_config():
     '''def __init__(self,name):
         #print 'aaaa'
         self.name = name
         print name
     '''
     def get_config(self,name):
         self.name = name
         config ={
             'testdb':{
                 'host':'192.168.6.6',
                 'user':'php2',
                 'passwd':'',
                 'db':'testdb',
                 'port':3307,
             },
         }
         return config[name]

2、自己封装的mysql 连接class db_mysql  先练练手。

 #/uer/bin/python                                                                                                                           

 import MySQLdb;
 from db_config import mysql_config
 m_config  = mysql_config()
 class db_mysql():
     def __init__(self):
         print 'class:db_mysql -import -true'

     def connect(self,name):
         #self.sql  = sql
         self.name = name
         try:
             #self.config = m_config.abc(name)
             config  = m_config.get_config(name)
             db = MySQLdb.connect(**config)
             cursor = db.cursor()
             #cursor.execute(sql)
         except MySQLdb.connector.Error as err:
             print("Something went wrong: {}".format(err))
         return cursor

     def execute(self,cursor,sql):
         cursor.execute(sql)
         return cursor

     def fetchall(self,cursor):
         data = cursor.fetchall()
         return data

     def fetchone(self,cursor):
         return cursor.fetchone()

3、测试能否获取到数据。。。。。。。

 #/usr/bin/python/                                                                                                                          

 from mysql import db_mysql
 mysql_obj = db_mysql()

 sql ="SELECT * FROM test WHERE `p_id` = '1000' LIMIT 10";
 cursor_connect  = mysql_obj.connect('testdb')
 cursor_execute  = mysql_obj.execute(cursor_connect,sql)
 data            = mysql_obj.fetchall(cursor_execute)

 print data;
