json.loads() (JSONDecodeError: Expecting value: line 1 column 1 (char 0))

I am trying to use json.load() but it is not working.

url = "http://api.worldbank.org/v2/country/all/indicator/" + ";".join(indicators) + 
source + date_range + per_page
response = requests.get(url)
print(response)
result = response.content
result = json.loads(result)
result

But I get this error any ideas?
error message

>Solution :

globalbank api defaults to XML, you need to tell it which format you need. try it like this:

url = "http://api.worldbank.org/v2/country/all/indicator/" + ";".join(indicators) + source + date_range + per_page + '&format=json'
