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)
