在Python中使用MySQL需要安裝MySQLdb，但從官方站點 http://sourceforge.net/projects/mysql-python/ 目前只能下載到只持Python2.5版的MySQLdb。本文介紹Windows下安裝MySQLdb的方法和常見問題處理。
Python2.6可以從http://www.python.org/download
下載官方的版本安裝，也可以http://www.activestate.com/activepython/下載ActivePython安裝，后者在windows下使用更加方便。
MySQLdb版本： MySQL-python-1.2.2.win32-py2.6.exe

>>> import MySQLdb
D:\usr\local\Python26\lib\site-packages\MySQLdb\__init__.py:34: DeprecationWarning: the sets module is deprecated
from sets import ImmutableSet
----------------------------------------------------------------------------------------------------
解決方法：
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
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,
