在Python中检索JSON的所有键

我知道这类问题已经得到了回答，但提供的解决方案根本不适合我。我希望在每个级别检索JSON文件中的所有键，而不仅仅是在第一个级别

假设我想从下面的JSON文件中获取所有密钥

{
    "quiz": {
        "sport": {
            "q1": {
                "question": "Which one is correct team name in NBA?",
                "options": [
                    "New York Bulls",
                    "Los Angeles Kings",
                    "Golden State Warriros",
                    "Huston Rocket"
                ],
                "answer": "Huston Rocket"
            }
        },
        "maths": {
            "q1": {
                "question": "5 + 7 = ?",
                "options": [
                    "10",
                    "11",
                    "12",
                    "13"
                ],
                "answer": "12"
            },
            "q2": {
                "question": "12 - 8 = ?",
                "options": [
                    "1",
                    "2",
                    "3",
                    "4"
                ],
                "answer": "4"
            }
        }
    }
}

我目前的进展

for k,v in json_object.items():
    print(v.keys())

将json内容作为dict存储在变量中，即

data

作为：

data = {
    "quiz": {
        "sport": {
            "q1": {
                "question": "Which one is correct team name in NBA?",
                "options": [
                    "New York Bulls",
                    "Los Angeles Kings",
                    "Golden State Warriros",
                    "Huston Rocket"
                ],
                "answer": "Huston Rocket"
            }
        },
        "maths": {
            "q1": {
                "question": "5 + 7 = ?",
                "options": [
                    "10",
                    "11",
                    "12",
                    "13"
                ],
                "answer": "12"
            },
            "q2": {
                "question": "12 - 8 = ?",
                "options": [
                    "1",
                    "2",
                    "3",
                    "4"
                ],
                "answer": "4"
            }
        }
    }
}

使用下面的递归方法获取所有键

def get_keys(d, indent=0, parent=""):
    print("{}{}{}{}".format(" "*indent*4, parent, " => " if parent else "", list(d.keys())))

    for key in d:
        if isinstance(d[key], dict):
            get_keys(d[key], indent=indent+1, parent=key)

当您按如下方式调用该方法时：

get_keys(data)                                                                                                                                                                                        

您将得到如下输出：

['quiz']
    quiz => ['sport', 'maths']
        sport => ['q1']
            q1 => ['question', 'options', 'answer']
        maths => ['q1', 'q2']
            q1 => ['question', 'options', 'answer']
            q2 => ['question', 'options', 'answer']

到目前为止你尝试了什么？@Gahan很抱歉，我没有添加我的进度，所以我只是问有人会如何从头开始处理问题。谢谢你的反馈。
