I have a nested dictionary with the following structure:

```
topHitsDict = 
{'record301': 
    {'query': 'OBGP2018240_Oncorhynchus.clarkii',
        'hit1': 
            {'description': 'OBGP-2018-240_Oncorhynchus.clarkii',
            'score': '340',
            'eval': '2e-94'},
        'hit2': 
            {'description': 'OBGP-2017-332_Oncorhynchus.clarkii',
            'score': '340',
            'eval': '2e-94'},
    'numTopHits': 2},
'record302': 
    {'query': 'OBGP2018248_Oncorhynchus.kisutch',
        'hit1': 
            {'description': 'OBGP-2018-248_Oncorhynchus.kisutch',
            'score': '340',
            'eval': '2e-94'},
        'hit2': 
            {'description': 'OBGP-2018-038_Oncorhynchus.kisutch',
            'score': '340',
            'eval': '2e-94'},
        'hit3': 
            {'description': 'OBGP-2017-271_Oncorhynchus.kisutch',
            'score': '340',
            'eval': '2e-94'},
    'numTopHits': 3},
'record303':
    {'query': 'OBGP2019056_Oncorhynchus.tshawytscha',
       'hit1':
            {'description': 'OBGP-2019-056_Oncorhynchus.tshawytscha',
            'score': '340',
            'eval': '2e-94'},
        'hit2':
            {'description': 'OBGP-2017-356_Oncorhynchus.tshawytscha',
            'score': '340',
            'eval': '2e-94'},
        'hit3': 
            {'description': 'OBGP-2017-052_Oncorhynchus.tshawytscha',
            'score': '340',
            'eval': '2e-94'},
    'numTopHits': 3},
'record304':
    {'query': 'OBGP2019190_Oncorhynchus.nerka',
        'hit1': 
            {'description': 'OBGP-2019-191_Oncorhynchus.nerka',
            'score': '340',
            'eval': '2e-94'},
        'hit2': 
            {'description': 'OBGP-2019-190_Oncorhynchus.nerka',
            'score': '340',
            'eval': '2e-94'},
    'numTopHits': 2}
}

```

And I want to access the 'description' keys in all of the hitx sub dictionaries.

I know I could use for loops, and I have tried the following thinking I could maybe keep it down to one for loop by looping through the recordx dictionaries and then accessing all of the 'description' keys in the hitx dictionaries within a recordx dictionary at one time, but I'm not having any success:

```
hits = dict(filter(lambda item: 'hit' in item[0], topHitsDict['record301'].items()))
seqs = dict(filter(lambda item: 'description' in item[0], hits.items()))

seqs
{}

```

Any and all help would be much appreciated!
