 连接MySQL数据库

源码

import MySQLdb #导入MySQLdb模块

print '连接数据库</br>'

#连接MySQL数据库 connect the database

#host处如果填写'localhost',报错的话,请尝试使用'127.0.0.1'

db=MySQLdb.connect(host='127.0.0.1',user='root',passwd='michael',db='test')

#获取数据库游标 get the database cursor

cur=db.cursor()

#执行SQL语句 execute the sql

r=cur.execute('select * from people')

#获取查询结果 get all the results selected

r=cur.fetchall()

#输出查询结果

print '输出数据库查询结果:</br>'

print r

#关闭游标 close the cursor

cur.close()

#关闭数据库连接 close the database connection

db.close()

附:Python中raw_input与input的区别

  1. raw_input获取用户输入之后的返回结果是一个字符串类型数据

    获取用户输入,转化为字符串类型,然后返回

  2. input获取用户输入之后的返回值是一个数值型的数据

    等价于eval(raw_input(提示信息))
