Python2 uses mysqldb handouts

This article is mainly introduced to you, hoping to supplement and update some knowledge, if you have other questions you need to know, you can continue to follow my updated article in the industry information.

PyMySQL is a library used to connect to MySQL CVM in the Python3.x version, while mysqldb is used in Python2

Without saying much, go directly to the code to illustrate the purpose.

#! / user/bin/env python

# coding=utf-8

From pymysql import connect,cursors

From pymysql.err import OperationalError

Import os

Import configparser as cparser

From builtins import int

From framework.logger import Logger

Import time

= read mysql configuration in config.ini file =

''

Base_dir = str (os.path.dirname (os.path.dirname (file)

File_path = base_dir + "\ config\ config.ini"

Cf = configUtil (file_path)

Host = cf.get ("sitmysqlconf", "host")

Port = cf.get ("sitmysqlconf", 'port')

Db = cf.get ("sitmysqlconf", 'db_name')

User = cf.get ("sitmysqlconf", 'user')

Password = cf.get ("sitmysqlconf", 'password')

Logger= Logger (logger= mysqlUtils). Getlog ()
