how do you update data dictionary in python

Question

I am going through a json file and extracing "name" and "id" field. I need to form a data dictionary and store "name" and "id" fields in data dictionary called my_dict

report=("'name':{}, 'id':{}.format(content['name',content['id']
print(report)

'name': report1, 'id':1

I need to create and data dictionary and update the dictory with report values

I tried this:

my_dict.update(report)

I am getting this error:

ValueError: dictionary update sequence element #0 has lenght1, 2 is required

You need to add more clarity. `print(report)` looks strange/incorrect, you'll need to explain what it is. (Is it a `list` of `dict`?) What is `my_dict` beforehand? What do you expect `my_dict` to be afterwards? — Kache, May 17 '23 at 19:53
`report` seems to be a string, not a dict; if this is confirmed, `my_dict.update(ast.literal_eval('{' + report + '}'))` should work. — Swifty, May 17 '23 at 19:59

In your original post, you have multiple identical keys. Keys must be unique. Also, to create a dictionary: `report = {"name": content["name"], "id": content["id"]}`. — 001, May 17 '23 at 20:02
That said, your formatted string seems strange. And what is `content` ? — Swifty, May 17 '23 at 20:07

Create a dictionary and update the dictionary with the report values:

contents = [{'name': 'Ted', 'id': 1}, {'name': 'Fred', 'id': 2}]

# empty dict
my_dict = {}  

# loop through contents and add to dict
for content in contents:
    name = content['name']
    id_value = content['id']
    my_dict[name] = id_value

print(my_dict)

Output:

{'Ted': 1, 'Fred': 2}
