Python爬取雪中悍刀行弹幕分析并可视化详程

哔哔一下

雪中悍刀行兄弟们都看过了吗？感觉看了个寂寞，但又感觉还行，原谅我没看过原著小说~

豆瓣评分5.8，说明我还是没说错它的。

当然，这并不妨碍它波播放量嘎嘎上涨，半个月25亿播放，平均一集一个亿，就是每天只有一集有点难受。

我们今天就来采集一下它的弹幕，实现数据可视化，看看弹幕文化都输出了什么~

爬虫部分

我们将它的弹幕先采集下来，保存到excel表格~

首先安装一下这两个模块

requests     # 发送网络请求
pandas as pd # 保存数据

不会安装模块移步主页看我置顶文章，有专门详细讲解安装模块问题。

代码部分

import requests     # 发送网络请求
import pandas as pd # 保存数据

headers = {
    'user-agent': 'mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/97.0.4692.71 safari/537.36'
}
# 构建一个列表储存数据
data_list = []
for page in range(15, 1500, 30):
    try:
        url = f'https://mfm.video.qq.com/danmu?otype=json&target_id=7626435152%26vid%3dp0041oidttf&session_key=0%2c174%2c1642248894&timestamp={page}'
        # 1. 发送网络请求
        response = requests.get(url=url, headers=headers)
        # 2. 获取数据 弹幕内容 <response [200]>: 告诉我们响应成功
        json_data = response.json()
        # print(json_data)
        # 3. 解析数据(筛选数据) 提取想要的一些内容 不想要的忽略掉
        comments = json_data['comments']
        for comment in comments:
            data_dict = {}
            data_dict['commentid'] = comment['commentid']
            data_dict['content'] = comment['content']
            data_dict['opername'] = comment['opername']
            print(data_dict)
            data_list.append(data_dict)
    except:
        pass
# 4. 保存数据 wps 默认以gbk的方式打开的
df = pd.dataframe(data_list)
# 乱码, 指定编码 为 utf-8 或者是 gbk 或者 utf-8-sig
df.to_csv('data.csv', encoding='utf-8-sig', index=false)

效果展示

数据可视化

数据到手了，咱们就开始制作词云图分析了。

这两个模块需要安装一下

jieba
pyecharts

代码展示

import jieba
from pyecharts.charts import wordcloud
import pandas as pd
from pyecharts import options as opts

wordlist = []
data = pd.read_csv('data.csv')['content']
data

data_list = data.values.tolist()
data_str = ' '.join(data_list)
words = jieba.lcut(data_str)

for word in words:
    if len(word) > 1:
        wordlist.append({'word':word, 'count':1})
df = pd.dataframe(wordlist)

dfword = df.groupby('word')['count'].sum()
dfword2 = dfword.sort_values(ascending=false)

dfword = df.groupby('word')['count'].sum()
dfword2 = dfword.sort_values(ascending=false)

dfword3['word'] = dfword3.index
dfword3

word = dfword3['word'].tolist()
count = dfword3['count'].tolist()

a = [list(z) for z in zip(word, count)]
c = (
    wordcloud()
    .add('', a, word_size_range=[10, 50], shape='circle')
    .set_global_opts(title_opts=opts.titleopts(title="词云图"))
)
c.render_notebook()

效果展示

词云图效果

可以看到，这条、暴富和最后三个评论数据最多，咱们看看统计数据。

视频讲解

所有步骤都在视频有详细讲解

python爬虫+数据分析+数据可视化（分析《雪中悍刀行》弹幕）

福利环节

弹幕和词云图都有了，没有视频就说不过去，代码我整出来了，大家可以自己去试试，我就不展示了，展示了你们就看不到了。
