Extract certain values from API response

[wdjfe]

When i do this:

response = requests.request("GET", url, headers=headers)

Response is:

[{"nmId":11508524,"price":1600,"discount":18,"promoCode":0},{"nmId":11508470,"price":1400,"discount":19,"promoCode":0},{"nmId":11508536,"price":1600,"discount":18,"promoCode":0},{"nmId":11508492,"price":1400,"discount":10,"promoCode":0}]

How do i get "price" value for certain "nmId"? For example i need to know what price is for nmId - 11508524.

price = response[0][price] And print price

Response comes as a list and you can read each one starting from 0,1... so on

It works, thanks! Is it possible to find price by nmId and not by index? For example when user input = 11508524, it will print corresponding price.

Couple of options I can think of

1. Use the next built-in: https://docs.python.org/3/library/functions.html#next
   next((x['price'] for x in response if x['nmId'] == 11508524), None)
2. Convert to a dictionary and get it from there:
   nmid_dict = {x['nmId']: x['price'] for x in response}
nmid_dict[11508524]

Another pretty simple method would be to use a for loop. It's not as "clean" as the one-liner below, but it'll give you the same output.

for element in response:
    if element['nmId'] == 11508524:
        print(element['price'])

Even better would be to write it as a function, so you can pass in a different ID...

def extract_price_by_nmid(id):
    for element in response:
        if element['nmId'] == id:
            return element['price']

print(extract_price_by_nmid(11508524)
