How to convert list to dictionary

a = [{ 'id': '123', 'name': 'A', 'type': 'software' },
     { 'id': '102', 'name': 'Adfds', 'type': 'software' },
     { 'id': '222', 'name': 'sxds', 'type': 'software' }]

Code is below

{{key:val} for each in a for key,val in each.items()}

Expected out

{ '123': { 'name': 'A', 'type': 'software' },
  '102': { 'name': 'Adfds', 'type': 'software' },
  '222': { 'name': 'sxds', 'type': 'software' } }

You can use map and lambda to achieve your goal. Just do:

result = dict(map(lambda entry: [entry.pop('id'), entry], a))
print(result)

And it gives:

{'123': {'name': 'A', 'type': 'software'}, '102': {'name': 'Adfds', 'type': 'software'}, '222': {'name': 'sxds', 'type': 'software'}}

You can do this:

{e['id']: dict(i for i in e.items() if i[0] != 'id') for e in a}

you can try this:

a=[{ 'id': '123', 'name': 'A', 'type': 'software' }, { 'id': '102', 'name': 'Adfds', 'type': 'software' }, { 'id': '222', 'name': 'sxds', 'type': 'software' }]

b = {}

for item in a:
    b[item.pop("id")] = item

b

output:

A dictionary cannot have duplicated keys.

In your example you are adding different values to same key. Here what you had to do:

res = {each["id"]: {"name": each["name"], "type": each["type"]} for each in a}
