Python 根据条件递归地向嵌套字典添加键

我有一个多级嵌套字典，每当字典中有type个键时，就try 添加一个键required.

Code:

def add_recursively(val):
   if 'type' in val and val['type'] != 'object':
      val['required'] = False
      return val
   elif 'type' in val and val['type'] == 'object' and 'object_schema' in val:
      return add_recursively(val['object_schema'])
   else:
     val['required'] = False
     return val

new_data = {}
for key, value in data.items():
    if value['type'] == 'object' and 'object_schema' in value:
       new_data[key] = add_recursively(value)
    else:
       value['required'] = False
       new_data[key] = value

Input data:

data = {'key1': {'description': 'Configuration for OpenID', 'type': 'boolean'},
 'key2': {'default': {'enabled': True, 'logging_percent': 100},
  'object_schema': {'enabled': {'default': True, 'type': 'boolean'},
   'logging_percent': {'default': 100, 'type': 'float'},
   'nested_key': {'default': {'new_enable': True, 'new_precent': 100},
    'object_schema': {'new_enable': {'default': True, 'type': 'boolean'},
     'new_precent': {'default': 100, 'type': 'float'}},
    'type': 'object'}},
  'type': 'object'}}

Output data:

{'key1': {'description': 'Configuration for OpenID',
  'required': False,
  'type': 'boolean'},
 'key2': {'enabled': {'default': True, 'type': 'boolean'},
  'logging_percent': {'default': 100, 'type': 'float'},
  'nested_key': {'default': {'new_enable': True, 'new_precent': 100},
   'object_schema': {'new_enable': {'default': True, 'type': 'boolean'},
    'new_precent': {'default': 100, 'type': 'float'}},
   'type': 'object'},
  'required': False}}

Expected output:

{'key1': {
  'required': False,
  'description': 'Configuration for OpenID',
  'type': 'boolean'},
 'key2': {
     'required': False,
     'enabled': {'required': False, 'default': True, 'type': 'boolean'},
    'logging_percent': {'required': False, 'default': 100, 'type': 'float'},
    'nested_key': {'default': {'new_enable': True, 'new_precent': 100},
    'object_schema': {'new_enable': {'required': False, 'default': True, 'type': 'boolean'},
      'new_precent': {'required': False, 'default': 100, 'type': 'float'}},
    'type': 'object'},
    }}
