Python dictionary of dictionaries get only primary keys

Question

I have a dictionary of dictionaries and want to get the Primary keys of it only. There is no way to eliminate the other keys by name.

That is an example dictionary:

{
'default': {
    'routes': '3',
    'paths': '3',
    'best_paths': {
        'broadcast': '3'
    },
    'backup_paths': {}
        },
'management': {
    'routes': '15',
    'paths': '15',
    'best_paths': {
        'local': '1',
        'direct': '1',
        'static': '1',
        'eigrp': '5'
    },
    'backup_paths': {}
        },
'test1': {
    'routes': '260',
    'paths': '275',
    'best_paths': {
        'local': '16',
        'direct': '16',
        'static': '1',
        'ospf': '33',
    },
    'backup_paths': {}
    },
}

The number of keys could be different. But the depths of dictionaries is always the same.

My expected result would be something like this

key_list = 'default', 'management', 'test1'

The answer of the question 'python JSON only get keys in first level' is not working.

`list(your_dictionary)` would give you that. There is nothing special about the values being dictionaries too here. — Martijn Pieters, Oct 16 '17 at 07:03
I tried dict.keys() and got all keys as output 'default', 'routes', 'paths' ... — Christoph N, Oct 16 '17 at 07:09
Just tried list(dict) as well and it's the same output 'default', 'routes', 'paths' ... — Christoph N, Oct 16 '17 at 07:14
The question got marked as duplicate but the result there is not working in my program. How can I get rid of the Duplicate marking that the question is open again? — Christoph N, Oct 16 '17 at 07:29
Well, it would help if you would fix your example to show the bad behavior ... I did x = {your dictionary}; list(x.keys()) returns ['management', 'default', 'test1'] — Foon, Oct 18 '17 at 21:53

Hi Keys function will give required output

dic={
'default': {
    'routes': '3',
    'paths': '3',
    'best_paths': {
        'broadcast': '3'
    },
    'backup_paths': {}
        },
'management': {
    'routes': '15',
    'paths': '15',
    'best_paths': {
        'local': '1',
        'direct': '1',
        'static': '1',
        'eigrp': '5'
    },
    'backup_paths': {}
        },
'test1': {
    'routes': '260',
    'paths': '275',
    'best_paths': {
        'local': '16',
        'direct': '16',
        'static': '1',
        'ospf': '33',
    },
    'backup_paths': {}
    },
}
print (dic.keys())

I tried the keys function but I got all keys including subkeys as a result. – Christoph N Oct 16 '17 at 07:08
you mean dic.keys() keys giving all keys ? what is python version ? In Python2.7 the above code gives only keys of main dictionary – Sandeep Lade Oct 16 '17 at 07:10
Version is Python 3.6.2 – Christoph N Oct 16 '17 at 08:05
I tried in 3.6.2 and it works perfectly fine. Can you plz copy paste the code in my answer and let me know the result ? – Sandeep Lade Oct 16 '17 at 13:47
