Python3学习：Error整理

一、与 MySQL 数据库连接

1. 关于编码

• 修改之前

conn = pymysql.connect(
            host = MySql_Host_ip,
            port = MySql_Port,
            user = MySql_User,
            passwd = MySql_Password,
            db = MySql_Db)

• 问题描述

UnicodeEncodeError: 'latin-1' codec can't encode characters in position 43-44: ordinal not in range(256)

pymysql是没有指定编码类型

• 修改之后

conn = pymysql.connect(
            host = MySql_Host_ip,
            port = MySql_Port,
            user = MySql_User,
            passwd = MySql_Password,
            db = MySql_Db,
            use_unicode = True,
            charset = "utf8")
