路飞学城Python-Day150

最近由于在忙别的事情,所以路飞的课程就往后延期了,感觉很难受,不过我还是依然坚持学下去,必须的

最近在忙的事情

1.进入了数据分析行业,需要学习更多的知识

2.开始对数据收集负责,写各种爬虫

3.对数据行业很感兴趣,于是建立了自己的vpn

爬虫课程:

豆瓣爬虫,github地址

# 1.使用任意代理IP进行如下操作
# 2.使用requests模块进行豆瓣电影的个人用户登录操作
# 3.使用requests模块访问个人用户的电影排行榜->分类排行榜->任意分类对应的子页面
# 4.爬取需求3对应页面的电影详情数据
# 5.爬取3对应页面中滚动条向下拉动2000像素后加载出所有电影详情数据,存储到本地json文件中或者相应数据库中
# 【备注】电影详情数据包括:海报url、电影名称、导演、编剧、主演,类型,语言,上映日期,片长,豆瓣评分
