Python爬取豆瓣电影评论，并用词云显示

Python爬取豆瓣电影评论，并用词云显示

1、分析

我们打开豆瓣网站，随便搜索一部电影，到详情页，这是我们观察地址

后面这一串数字就是这部电影的id

2、需要用到的库

1、requests库，最经典的爬虫库
2、jieba库，经典的中文分词库
3、stylecloud库，生成图云

完整代码如下：

# 分析豆瓣唐探3的影评，生成词云
# https://movie.douban.com/subject/27619748/comments?start=20&limit=20&status=P&sort=new_score
# url = 'https://movie.douban.com/subject/%s/comments?start=%s&limit=20&sort=new_score&status=P '\
# % (movie_id, (i - 1) * 20)
