python script returns multiple data, how to get the first data and download it

Question

My script is

import requests
from requests.auth import HTTPBasicAuth
import json
url = "https://your-domain.atlassian.net/rest/api/2/issue/{issueIdOrKey}"

auth = HTTPBasicAuth("[email protected]", "<api_token>")

headers = {
   "Accept": "application/json"
}

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

print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))

And get the response body, the format as below:

{
        "startAt":0
        "comment":[
            {
                "self": "xxxx",
                "id": "xxx",
                "body": "daily in URLlink"
            },
            {
                "self": "xxxx",
                "id": "xxx",
                "body": "daily in URLlink"
            },
            ...
        ]
    }

And I need to get the first data in the comment(The URLlink in the body).

The URLlink is download link, I want to download the URLlink content automatically by script.

Update1

import requests
from requests.auth import HTTPBasicAuth
import json
url = "https://your-domain.atlassian.net/rest/api/2/issue/{issueIdOrKey}"

auth = HTTPBasicAuth("[email protected]", "<api_token>")

headers = {
   "Accept": "application/json"
}

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

print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))

url = responsed["comment"][0]["body"]

r = requests.get(url, allow_redirects=True)

open('file_name', 'wb').write(r.content)

And get the error:

Then I add import responsed, get the latest error.

Update2

Now, update the python script, it as below:

import requests
from requests.auth import HTTPBasicAuth
import json
#import responsed

url = "https://your-domain.atlassian.net/rest/api/2/issue/{issueIdOrKey}"

auth = HTTPBasicAuth("[email protected]", "api_token")

headers = {
   "Accept": "application/json"
}

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

#print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))

url = response.json()['comments'][0]["body"]

And it response body format like:

daily build in URLDownloadLink

Before this, I need to click URLDownloadLink download it.

And now, I want to achieve automatic download. Thx
