如何在Python中遍历JSON对象并获取KEY？

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

# 示例JSON对象
json_obj = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Street",
        "city": "New York"
    },
    "hobbies": ["reading", "coding"]
}

# 获取所有KEY
keys = get_keys(json_obj)
print(keys)

['name', 'age', 'address', 'street', 'city', 'hobbies']
