如何从 Python 中的 Yelp API 请求中获得 3 条评论？

Question

Hi I am trying to extract exactly 3 reviews for a list of businesses that I already have business ids. So far I have written this much of the code. I need a function that would specifically retrieve business review from yelp API. Please let me know what function can be create to add to this that would retrieve the same. thanks

Answer 1

Are you looking for something like this?

def get_three(id1, id2, id3):
    return [get_business(API_KEY, id) for id in [id1, id2, id3]]

Answer 2

Yelp Reviews API Endpoint returns up to 3 reviews. There's no need to filter anything, just use it and it'll return at max 3 results.
