学python好久了，也没写过脚本，先来个mysql数据库的查询脚本吧.

1.首先要安装MySQLdb

[root@python ~]# pip install MySQL-python

import MySQLdb

def python_mysql_query():

    #Open the database connection
    db = MySQLdb.connect(host=‘localhost‘,user=‘ossec‘,passwd=‘mysql0123‘,db=‘ossec‘,port=3306, charset=‘utf8‘)

    #Gets the operation cursor
    cursor = db.cursor()

    #SQL statement query
    #sql = "select * from data where id < ‘%d‘" % (5)
    sql = "select * from data limit 5"

    try:
        #Execute the SQL statement
        cursor.execute(sql)
        
        #Receive all return results
        results = cursor.fetchall()
        
        #Traverse the print list
        for i in results:
            print i
    
    except:
        print "Error: unable to fecth data"

    #Close the cursor
    cursor.close()
    
    #Close the database connection
    db.close()

if __name__==‘__main__‘:
    python_mysql_query()
