How can I write a python crawler about searching for answers from scratch?

I plan to learn python for the course next semester. It is said that it is faster to directly create a small project than to learn syntax first. Therefore, I plan to create the following small program and do not know how difficult it is to implement and what knowledge points are needed, I hope you can give me some guidance. Thank you very much: In the answer to zhihu's mathematical classification, filter out more than 10 answers with 500 likes (that is to say, if there are 10 answers with more than 500 likes under a question, the conditions are met ). I can write only one class in java at the highest level. I will start to learn it myself next semester because I need python for the course.

I can only write a game similar to Tetris in java at the highest level. C ++. I have never been familiar with python, and have no experience in intercepting links on webpages. I don't know how difficult the above ideas are for beginners. I hope you can give me some guidance. For example, links to required knowledge points and blogs. Thank you very much.
