原文：http://www.the5fire.com/python-opt-mysql.html 1、增：

import MySQLdb

conn = MySQLdb.connect(db='test',host='127.0.0.1',user='root',passwd='root')
curs = conn.cursor()

sql_insert = 'INSERT INTO books(title) VALUES("book2")'
curs.execute(sql_insert)
conn.commit()

2、删：

sql_delete = 'DELETE FROM books WHERE id = 1'
curs.execute(sql_delete)

3、改：

sql_update = 'UPDATE books SET title = "bookupdate" WHERE id = 1'
curs.execute(sql_update)

4、查：

sql_select = 'SELECT * FROM books'
curs.execute(sql_select)
rows = curs.fetchall()
for row in rows:
    print row[1]
