python - 如何递归迭代复杂的python对象？

Question

我有这样的对象:

et = {  
    "applications": [
        {
        "applications_application": 'value',
        "application_journalNumber": 'value',
        "appParticipants": [
            {
                "appParticipant_inn": "value",
                "appParticipant_kpp": "value",
                "legalForm_code": "value"
            }
            ]
        }
    ]
}

我需要递归地遍历它的所有键。我怎样才能做到呢？我想要得到类似的东西:

applications
applications_application
application_journalNumber
appParticipants
appParticipant_inn
appParticipant_kpp
legalForm_code

我的不起作用的解决方案:

def myprint(d):
    for k, v in d.items():
      if isinstance(v, dict):
        myprint(v)
      else:
        if isinstance(v, list):
            myprint(v[0])

附注每个数组中只有一项。

怎么样:

def traverse_dict(d):
    keys = []
    for key, item in d.items():
        keys.append(key)
        if isinstance(item, dict):
            keys.extend(traverse_dict(item))
        elif isinstance(item, list):
            for d in item:
                keys.extend(traverse_dict(d))
    return keys
