python 加入子词典

Question

我正在尝试在 python 中加入子字典，以便有效的 json 组成我所拥有的是：

{
'ctx/language': 'en',
'ctx/territory': 'DE',
'composer_name': 'openEHR2study',
'Allergies': {
    'adverse_reaction-allergy': [{
            'reaction_event_summary': {
                'clinical_impact': [{
                        '|code': 'at0035'
                    }
                ]
            }
        }, {
            'recorded': ['2020-05-14T00:00:00.000Z']
        }, {
            'reaction_event_summary': {
                'certainty': [{
                        '|code': 'at0024'
                    }
                ]
            }
        }, {
            'substance_agent': ['s']
        }, {
            'reaction_reported': ['true']
        }, {
            'comment': ['c']
        }
    ]
}

}

我想要的是像这样加入“reaction_event_summary”：

{
'ctx/language': 'en',
'ctx/territory': 'DE',
'composer_name': 'openEHR2study',
'Allergies': {
    'adverse_reaction-allergy': [{
            'reaction_event_summary': {
                'clinical_impact': [{
                        '|code': 'at0035'
                    }
                ]
                 'certainty': [{
                        '|code': 'at0024'
                    }
                ]
            }
        }, {
            'recorded': ['2020-05-14T00:00:00.000Z']
        }, {
            'substance_agent': ['s']
        }, {
            'reaction_reported': ['true']
        }, {
            'comment': ['c']
        }
    ]
}

我不知道我应该如何遍历 json/list 和 dicts 来完成这项工作。

我做了一个粗略的尝试，请检查这是否有效。 我们正在尝试用另一个 deepcopy 迭代字典。

val = {
    'ctx/language': 'en',
    'ctx/territory': 'DE',
    'composer_name': 'openEHR2study',
    'Allergies': {
        'adverse_reaction-allergy': [
            {
                'reaction_event_summary': {
                    'clinical_impact': [{
                        '|code': 'at0035'
                    }
                    ]
                }
            }, {
                'recorded': ['2020-05-14T00:00:00.000Z']
            }, {
                'reaction_event_summary': {
                    'certainty': [{
                        '|code': 'at0024'
                    }
                    ]
                }
            }, {
                'substance_agent': ['s']
            }, {
                'reaction_reported': ['true']
            }, {
                'comment': ['c']
            }
        ]
    }
}

import copy

val1 = copy.deepcopy(val)
del val1['Allergies']['adverse_reaction-allergy']
val1['Allergies']['adverse_reaction-allergy'] = []
reaction_count = 0

for _d in val['Allergies']['adverse_reaction-allergy']:
    if _d.get('reaction_event_summary', False):
        if reaction_count < 1:
            reaction_count += 1
            val1['Allergies']['adverse_reaction-allergy'].append(
                {'reaction_event_summary': _d.get('reaction_event_summary')})
        else:
            print(_d.get('reaction_event_summary'))
            _temp = val1['Allergies']['adverse_reaction-allergy'][0]['reaction_event_summary']
            _temp['certainty'] = _d.get('reaction_event_summary',{}).get('certainty',{})
            val1['Allergies']['adverse_reaction-allergy'][0]['reaction_event_summary'] = _temp
    else:
        val1['Allergies']['adverse_reaction-allergy'].append(_d)
import json
print(json.dumps(val1, indent=2))
