fetch from json file (Python)

x = json.load(open('Download.json'))
for sub_dict in x['result']:
    print('model', sub_dict["model"])
    for entry in sub_dict['model']:
        print(entry['downloadSize'])

Error:

    print(entry['downloadSize'])
TypeError: string indices must be integers

I can not get the value of downloadurl in any way. How to contact him correctly?

    print('model', sub_dict["model"])
    print(sub_dict['model']['downloadSize'])

sub_dict[‘model’] is a dictionary not a list

so when you do for entry in sub_dict['model'] that is the same as

for key in sub_dict['model'].keys() each "entry" in that iteration is just a string that is a key to the sub_dict[‘model’] dictionary
