It has been several days since "later we" was released. I haven't been to see it. There was a ticket refund incident a few days ago. The theme song of the movie was sung by Eason Chan. I specially looked for the MV of the theme song "we" and watched it. It's still that feeling. That day, I saw an official account of the Python Chinese community public. New discovery of 100000 comments on Eason Chan's new song "we" in Python . Recently, I have been learning Python, trying to find an interesting project to do an exercise, so I started to practice by imitating the author's code. In the original, the author said in the title "new discovery of 100000 comments". Through the operation of the program, I found that the author didn't crawl all comments, just crawled the popular comments of "we" in Netease cloud music, and according to the number According to the chart.
