Installation:

https://pypi.org/project/get_set_nested_dict/

pip install get_set_nested_dict

Usage:

nested_dict = {
  "key": [
    {
      "sub_key": {
        "sub_sub_key_1": "Value_1",
        "sub_sub_key_2": "Value_2"
      }
    }
  ]
}

before:

sub_sub_value_1 = nested_dict['key'][0]['sub_key']['sub_sub_key_1']

after:

from get_set_nested_dict import get_set_nested_dict
nested_dict, sub_sub_value_1 = get_set_nested_dict(nested_dict, "key[0].sub_key.sub_sub_key_1")

Example:

nested_dict = {
  "club": [
    {
      "manager": {
        "last_name": "Lionel",
        "first_name": "Messi"
      }
    }
  ]
}

before:

manager_last_name = nested_dict['club'][0]['manager']['last_name']
nested_dict['club'][0]['manager']['last_name'] = 'Pulga'

after:

from get_set_nested_dict import get_set_nested_dict
path = "club[0].manager.last_name"
nested_dict, manager_last_name = get_set_nested_dict(nested_dict, path, setter_value='Pulga')

>>> nested_dict
{'club': [{'manager': {'last_name': 'Pulga', 'first_name': 'Messi'}}]}
>>> manager_last_name
'Lionel'
