Python print only .jpg url's from json

November 5, 2022

How can I print only .jpg/.png urls from API using json?

import requests
import json

r = requests.get("https://random.dog/woof.json")
print("Kod:", r.status_code)

def jprint(obj):
    text = json.dumps(obj, sort_keys=True, indent=4)
    print(text)

jprint(r.json())

Results:

{
    "fileSizeBytes": 78208,
    "url": "https://random.dog/24141-29115-27188.jpg"
}

I tried .endswith() but without any success.
I’m beginner.

>Solution :

This example will use str.endswith to check, if dictionary value under the key url contains the string .jpg or .png.

I’m doing 10 requests and using time.sleep to wait 1 second between each request:

import requests
from time import sleep

url = "https://random.dog/woof.json"

for i in range(10):
    print("Attempt {}".format(i + 1))

    data = requests.get(url).json()
    if data["url"].endswith((".jpg", ".png")):
        print(data["url"])

    sleep(1)

Prints (for example, data returned from the server is random):
