How to get exactly 3 reviews from Yelp API request in python?

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.
