目前python3还没有连接数据库的模块。本文主要讲述python2.6在windows下连接mysql的环境搭建。

     python2.6.3下载：http://www.python.org/download/releases/2.6.3/

     首先安装MySQL for Python模块。

     MySQLdb版本： MySQL-python-1.2.2.win32-py2.6.exe

     地址：http://home.netimperia.com/files/misc/MySQL-python-1.2.2.win32-py2.6.exe
    

     安装好后遇到的常见问题：

1、ImportError: DLL load failed: 找不到指定的模块

--------------------------------------------------------

>>> import MySQLdb
Traceback (most recent call last):
  File “<stdin>”, line 1, in <module>
  File “D:\Program Files\Python2.6\Lib\site-packages\MySQLdb\__init__.py”, line 19, in <module>

    import _mysql
ImportError: DLL load failed: 找不到指定的模块。

--------------------------------------------------------

解决方法：下载libmmd.dll和libguide40.dll两个dll文件并复制到python安装目录的Lib\site-packages下。

2、ImportError: DLL load failed: 找不到指定的模块。

>>> import MySQLdb
D:\Program Files\Python2.6\lib\site-packages\MySQLdb\__init__.py:34: DeprecationWarning: the sets module is deprecated
  from sets import ImmutableSet

--------------------------------------------------------

解决方法：
1) file “__init__”, replace: 
 
from sets import ImmutableSet  
class DBAPISet(ImmutableSet):  
 
with  
 
class DBAPISet(frozenset) 
 
2) file “converters.py”, remove: 
 
from sets import BaseSet, Set 

from sets import ImmutableSet
 
3) file “converters.py”, change “Set” by “set” (IMPORTANT: only two places): 
 
line 48: return set([ i for i in s.split(',') if i ]) 
line 128: set: Set2Str,
