如果添加上MySQL数据库创建脚本，就完美了

你好，我初次接触python,环境都是刚搭好，用户的Python3.5
在我运行view_spider 遇到如下错误，其他的author_spider fanyi_spider 都正常，麻烦能帮忙看看嘛。 万分感谢。

你好，在运行在view_spider时，写入数据库之前的数据是正确的，但是写入数据库，并不能通过Navicat读出，且通过命令行是输出如下的数据：
“(u'view_18335', '\xe6\x9d\xa8\xe7\x99\xbd\xe8\x8a\xb1\xe5\x94\x90\xe4\xbb\xa3\xef\xbc\x9a\xe6\x9f\xb3\xe5\xae\x97\xe5\x85\x83\xe6\x9d\xa8\xe7\x99\xbd\xe8\x8a\xb1\xef\xbc\x8c\xe9\xa3\x8e\xe5

请问这是什么原因？十分感谢！
