Answer 1

After climbing down, just add it in excel, or if there is ranking information on the crawled page, then combine it with the top string

Answer 2

250 has an API interface, and you can get everything by parsing json.

Answer 3

It’s so simple, just make a new list, use a for loop to put the name to be added to top, define an i variable topi and add it in front of the name, right?

Answer 4

Is this so
