首先，安装需要的环境，Mysql和Python就不说了，必备的东西。 主要是安装的MySQLdb，可以去sf.net下载，具体地址是http://sourceforge.net/projects/mysql-python/ 如果用Ubuntu，直接 sudo apt-get install python-mysqldb 安装完成之后可以在Python解释器中测试一下 输入 Python代码 import MySQLdb #注意大小写！！ 如果不报错，就证明安装成功了，可能继续了 MySQLdb在Python中也就相当于JAVA中的MySQL的JDBC Driver，Python也有类似的数据接口规范Python DB API，MySQLdb就是Mysql的实现。操作也比较简单和其它平台或语言操作数据库一样，就是建立和数据库系统的连接，然后给数据库输入SQL，再从数据库获取结果。 先写一个最简单的，创建一个数据库： #!/usr/bin/env python #coding=utf-8 ################################### # @author peng # @date 2012-05-17 ################################## #MySQLdb 示例 # ################################
