Posted 2020-09-25

1.MySQLdb 是用于Python链接Mysql数据库的接口，它实现了 Python 数据库 API 规范 V2.0，基于 MySQL C API 上建立的。

2.Python下MySQLdb安装。

  (1)先下载MySQLdb安装包，解压。

  (2)cmd以管理员身份运行，进行MySQLdb目录，将MySQLdb安装至Python下：python setup.py install

 He.py代码:

#coding=utf-8

import pymysql

conn=pymysql.connect(host="127.0.0.1",port=3306,user="root",passwd="root",db="dgcms",charset="utf8")
cur=conn.cursor()
sql="select * from blog"
cur.execute(sql)
rows = cur.fetchall()
for dr in rows:
    print(dr)

调用代码:
