What is the barrage of the spirit cage saying#

Overview##

The art painting of "Ling Cage" was produced in the first place, and it was broadcast exclusively on station B. The production in the national comics is excellent, but the plot has too many flaws. Comments are polarized, with good ones saying very good and bad ones saying very bad. See what the barrage says

Ideas

Crawl barrage through crawlers
Use jieba word segmentation to segment the barrage
Draw word cloud through wordcloud

Libraries used

csv is used for writing csv files
request is used to request the URL
The re regular library is used to extract the letter information in html
jieba is used for participle of Chinese characters
wordcloud for word cloud drawing

Code ideas come from python learners at station B

result##

The biggest word in the drawn word cloud is fear and being caught off guard. If you are afraid, look at P Yo.
