python3中pymysql模块查询显示的类以及有无缓存的类

# cursorclass 默认的值 pymysql.cursors.Cursor，结果也用for循环

# cOnn= pymysql.connect(host='127.0.0.1', port=3306, user='root', passwd='123456', db='数据库名称, charset='utf8', cursorclass=pymysql.cursors.DictCursor)

# 默认类

                 print(i)

                #如果返回是字典形式用 print['字典中的键']
