Python sort dictionary using key

Question

Python sort dictionary. I want to sort the below dictionary using name key.

I try this but not working.

{k: v for k, v in sorted(mydict.items(), key=lambda item: item[1])}

Sample dictionary

[
        {
            'id': 34, 
            'pid': 7, 
            'name': '1.1. Data Foo', 
            'open': 'open',
            'children' : [
                {
                    'id': 23,
                    'pid': 89,
                    'name': '1.1.1. Data 4',
                    'open': 'open'
                },
                {
                    'id': 23,
                    'pid': 89,
                    'name': '1.1.4. Data 6',
                    'open': 'open'
                },
                {
                    'id': 23,
                    'pid': 89,
                    'name': '1.1.2. Data 14',
                    'open': 'open'
                },
            ]
        }, 
        {
            'id': 32, 
            'pid': 7, 
            'name': '1.3. Data Bar',
            'open': 'open',
            'children' : [
                {
                    'id': 23,
                    'pid': 89,
                    'name': '1.2.1. Data 14',
                    'open': 'open'
                },
                {
                    'id': 23,
                    'pid': 89,
                    'name': '1.4.4. Data 86',
                    'open': 'open'
                },
                {
                    'id': 23,
                    'pid': 89,
                    'name': '1.0.2. Data 114',
                    'open': 'open'
                },
            ]
        }, 
        {
            'id': 33, 
            'pid': 7, 
            'name': '1.2. Data Rex'
             'open': 'open',
            'children' : [
                {
                    'id': 23,
                    'pid': 89,
                    'name': '2.1.1. Data 4o0',
                    'open': 'open'
                },
                {
                    'id': 23,
                    'pid': 89,
                    'name': '14.1.4. Data 676',
                    'open': 'open'
                },
                {
                    'id': 23,
                    'pid': 89,
                    'name': '1.11.2. Data 1423',
                    'open': 'open'
                },
            ]
        },
    ]

That's not a dictionary. That's a list (of dictionaries). It's quite different. Do you want to sort a list based on values of the dicts inside it? — Manuel Fedele, May 05 '20 at 11:37
@MilesDavis yes I want to sort alphabetically using name key — rahul.m, May 05 '20 at 11:38
there are multiple `name` keys. do you mean the ones that are on the same level as `pid`? — gold_cy, May 05 '20 at 11:42

Assuming that you want to sort by the name in the first level of each item in the list, the following one-liner will sort it.

a_list.sort(key=lambda x: x['name'])

yes just as your code – rahul.m May 05 '20 at 11:48
I am sorry but I do not understand your last comment. – Srikant May 05 '20 at 11:51
I try your code without changing – rahul.m May 05 '20 at 11:52
Try `print(a_list)` after the above line. – Srikant May 05 '20 at 11:53
