使用requests与lxml爬取豆瓣正在上映电影

利用requests库与lxml解析，获取豆瓣电影展示的所有正在上映的电影。没有进行进一步详情查看。因此比较简单。

结果展示

所有单个正在上映电影信息以字典存储，并整合在一张列表里。整理后格式如下：

   [ {
        'title': '反贪风暴4',
        'score': '6.3',
        'duration': '100分钟',
        'actors': '古天乐/郑嘉颖/林峯',
        'thumbnail': 'https: //img3.doubanio.com/view/photo/s_ratio_poster/public/p2551353482.jpg'
    },{...},{...},....]
