Return nested json string in Python-CodePudding

I'm trying to return and store a nested JSON string in Python which I intend to use to serve the image from the URL string in my program. The JSON payload is this:

{
"results": [{
        "id": "Some ID",
        "title": "Some Title",
        "content_description": "Some Description",
        "media": [{
                "gif": {
                    "url": "https://somemediasite.com/image.gif",
                    "dims": [
                        212,
                        256
                    ],
                    "preview": "https://somemediasite.com/imagePreview.gif",
                    "size": 484133
                        }
                    }
                    ]
            }
    ]
}

I want my program to return the "url" string when it runs but I'm having trouble figuring out how. Here is what I've got:

apikey = "myApiKey"
lmt = 1
search_term = aValuePassedFromAnotherMethod
r = requests.get(
            "https://somemediasite.com/random?q=%s&key=%s&limit=%s" % (search_term, apikey, lmt))
if r.status_code == 200:
    images = json.loads(r.content)
    for image in images["results"]["media"]:
        print(images.get('preview'))

Running it gives me the error TypeError: list indices must be integers or slices, not str

CodePudding user response：

There are two lists to loop over, first the results then the images. You also forgot "gif".

    for result in images["results"]:
        for image in result["media"]:
            print(image["gif"]["preview"])
