            "height": 412, 
            "type": "p",

        "aid": -3, 
        "owner_id": 14793
      }, 
      "type": "photo"
    }
  }
}

I stuck with

photos = json.load(open('photos.json'))['response']

Dont know how to use the for method in this case asdfsdfsdafsdafdsfdsfdsfdsfsdfsdafsadfsdafsdafsdafsadfs

Answer 1

Say x is the dictionary you provided.

x = json.load(open('photos.json'))['response']

This would be the way to extract sources:

sizes = [x[elem]['photo']['sizes'] for elem in x]
srcs = []
for size_list in sizes:
    for size_element in size_list:
        srcs.append(size_element['src'])

Answer 2

photos = json.load(open('photos.json'))['response']
src = [i['photo']['sizes'][0]['src'] for i in photos.values()]

src will store a list of all the values.

PS : You could pull off a one-liner too, but it would look really messy
