Preface
Recently, the first season of the TV series "the knife in the Snow" has been broadcast, and the audience's expectations for the show can be seen from the number of broadcasts. The total number of broadcasts has reached 5 billion, but unfortunately, Douban's score is only 5.7. it doesn't even break 6.
Many people will compare this play with "Qingyu year" because the creator has the same crew.

Today, let's collect some of the video barrage of the show to see what the audience said and why the number of broadcasts is high, but word of mouth is low.
Introduction of knowledge points
The use of requests module
Pandas saves tabular data
Visualization of word Cloud Picture by pyecharts
Environment introduction
Python 3.8
Pycharm
Requests > > pip install requests
Pyecharts > > pip install pyecharts
Code implementation 1. The import module import reimport requests # sends a network request import pandas as pd # to save data 2. Send a network request 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'} # build a list to store data data_list = [] for page in range (15, 1500, 30): url= f 'https://mfm.video.qq.com/danmu?otype=json&target_id=7626435152%26vid%3Dp0041oidttf&session_key=0%2C174%2C1642248894×tamp={page}' esponse = requests.get (url=url, headers=headers) 3. Get data on-screen comment content json_data = response.json ()
Tell us that the response was successful
4. Parse data (filter data) extract something you want to ignore comments = json_data ['comments'] print (comments) for comment in comments: data_dict = {} data_dict [' commentid'] = comment ['commentid'] content = comment [' content'] content = re.sub (r'[\ X0e\ xa0]','' Content) data_dict ['content'] = content data_dict [' opername'] = comment ['opername'] print (data_dict) data_list.append (data_dict) 5. Save data df = pd.DataFrame (data_list) # garbled, and specify either utf-8 or gbk or utf-8-sigdf.to_csv ('data.csv', encoding='utf-8-sig')
6.
