python2和python3 分别连接MySQL的代码

python2中的写法如下：

#coding=utf-8
import MySQLdb

try:
    conn = MySQLdb.connect(host='localhost', port=3306, db='python3', user='root', passwd='mysql', charset='utf8')
    cursor1 = conn.cursor()

    sql = 'insert into students(name) values("郭小二")'
    cursor1.execute(sql)
    conn.commit()

    cursor1.close()
    conn.close()
except Exception, e:
    print(e.message)

python3中的写法如下：

import pymysql

try:
    conn = pymysql.connect(host='localhost', port=3306, db='python3', user='root', passwd='mysql', charset='utf8')
    cursor1 = conn.cursor()

    sql = 'insert into students(name) values("郭小二")'
    cursor1.execute(sql)
    conn.commit()

    cursor1.close()
    conn.close()
except Exception:
    print(e.message)
