Sometimes we can get empty array when we are trying to parse server response response.json()["data"]
So, it would be great to check the array before we access it by index

Clean Code it works great

Its giving a 403 response code

@angelabauer are you able to help with KeyError: 'data' issues?

/usr/bin/python3.9 /home/schmacky/Projects/flight checker/main.py

data = response.json()["data"][0]
KeyError: 'data'

Process finished with exit code 1

the response.json() I'm getting from KIWI is either exactly what I'm expecting or it's
"{'status': 'Bad Request', 'error': 'unknown partner provided - if you would like to cooperate with Kiwi.com, please register at tequila.kiwi.com'}".
I'm having it repeat the request for each city with a for loop so nothing changes per iteration but the destination city (I've tried to only supply required parameters), yet it randomly works and randomly doesn't with the exact same code, run multiple times, it seems entirely random if it works or not. Any clue why? It has given a proper response with an empty list for "data" as well, it just randomly (although its most of the time) responds with said error.

Since Sheety allows 200 requests per month for free accounts delete a few entries in the Google sheet to save the requests. Currently, there are 11 entries so every time we run the code it takes 11 requests.
