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,
