遍历嵌套的JSON对象并遍历获取值

def traverse_json(json_obj):
    if isinstance(json_obj, dict):
        for key, value in json_obj.items():
            if isinstance(value, (dict, list)):
                traverse_json(value)
            else:
                print(key + ": " + str(value))
    elif isinstance(json_obj, list):
        for item in json_obj:
            traverse_json(item)

# 示例JSON对象
json_data = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Street",
        "city": "New York"
    },
    "children": [
        {
            "name": "Tom",
            "age": 5
        },
        {
            "name": "Emma",
            "age": 8
        }
    ]
}
