迭代json数据更新字典

import json

def update_dict(json_data, dictionary):
    if isinstance(json_data, dict):
        for key, value in json_data.items():
            if isinstance(value, (dict, list)):
                update_dict(value, dictionary)
            else:
                dictionary[key] = value
    elif isinstance(json_data, list):
        for item in json_data:
            update_dict(item, dictionary)

# 示例JSON数据
json_data = '''
{
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York"
    },
    "hobbies": ["reading", "traveling"]
}
'''

# 初始化字典
dictionary = {}

# 解析JSON数据并更新字典
data = json.loads(json_data)
update_dict(data, dictionary)

# 打印更新后的字典
print(dictionary)
