需要安裝MySQLdb，windows下安裝需要下載setup文件。

#!/usr/bin/python

import MySQLdb
def doInsert(cursor,db):
insert
Prepare SQL query to INSERT a record into the database.
sql = "UPDATE EMPLOYEE SET AGE = AGE+1 WHERE SEX = '%c'" %('M')
  try:
    cursor.execute(sql)
    db.commit()
  except:
    db.rollback()
def do_query(cursor,db):
  sql = "SELECT * FROM EMPLOYEE \
          WHERE INCOME > '%d'" % (1000)
  try:

  # Execute the SQL command
 cursor.execute(sql)
 # Fetch all the rows in a list of lists.
 results = cursor.fetchall()
 print 'resuts',cursor.rowcount
 for row in results:
    fname = row[0]
    lname = row[1]
    age = row[2]
    sex = row[3]
    income = row[4]
    # Now print fetched result
    print "fname=%s,lname=%s,age=%d,sex=%s,income=%d" % \

  sql = "INSERT INTO EMPLOYEE(FIRST_NAME, \
       LAST_NAME, AGE, SEX, INCOME) \
       VALUES ('%s', '%s', '%d', '%c', '%d' )" % \

Open database connection
change this to your mysql account
connect(server,username,password,db_name)
db = MySQLdb.connect("localhost","hunter","hunter","pydb" )
prepare a cursor object using cursor() method
cursor = db.cursor()
do_query(cursor,db)
doInsert(cursor,db)
do_query(cursor,db)
do_delete(cursor,db)
do_query(cursor,db)
do_insert(cursor,db,'hunter','xue',22,'M',2000)
do_insert(cursor,db,'mary','yang',22,'f',5555)
do_insert(cursor,db,'zhang','xue',32,'M',5000)
do_insert(cursor,db,'hunter','xue',22,'M',333)
do_query(cursor,db)
disconnect from server
db.close()</pre>
