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

 1 #/usr/bin/python
 2 
 3 class mysql_config():
 4     ‘‘‘def __init__(self,name):
 5         #print ‘aaaa‘
 6         self.name = name
 7         print name
 8     ‘‘‘
 9     def get_config(self,name):
10         self.name = name
11         config ={
12             ‘testdb‘:{                                                                                                            
13                 ‘host‘:‘192.168.6.6‘,
14                 ‘user‘:‘php2‘,
15                 ‘passwd‘:‘123456‘,
16                 ‘db‘:‘testdb‘,
17                 ‘port‘:3307,
18             },
19         }
20         return config[name]

2、自己封装的mysql 连接class db_mysql  先练练手。

 1 #/uer/bin/python                                                                                                                           
 2 
 3 import MySQLdb;
 4 from db_config import mysql_config
 5 m_config  = mysql_config()
 6 class db_mysql():
 7     def __init__(self):
 8         print ‘class:db_mysql -import -true‘
 9 
10     def connect(self,name):
11         #self.sql  = sql
12         self.name = name
13         try:
14             #self.config = m_config.abc(name)
15             config  = m_config.get_config(name)
16             db = MySQLdb.connect(**config)
17             cursor = db.cursor()
18             #cursor.execute(sql)
19         except MySQLdb.connector.Error as err:
20             print("Something went wrong: {}".format(err))
21         return cursor
22         
23     def execute(self,cursor,sql):
24         cursor.execute(sql)
25         return cursor
26 
27     def fetchall(self,cursor):
28         data = cursor.fetchall()
29         return data
30         
31     def fetchone(self,cursor):
32         return cursor.fetchone()

3、测试能否获取到数据。。。。。。。

 1 #/usr/bin/python/                                                                                                                          
 2 
 3 from mysql import db_mysql
 4 mysql_obj = db_mysql()
 5 
 6 sql ="SELECT * FROM test WHERE `p_id` = ‘1000‘ LIMIT 10";
 7 cursor_connect  = mysql_obj.connect(‘testdb‘)
 8 cursor_execute  = mysql_obj.execute(cursor_connect,sql)
 9 data            = mysql_obj.fetchall(cursor_execute)
10 
11 print data;
