如何在没有重复代码的情况下填充JSON对象的一部分？

import json

# 原始的JSON对象
original_json = '''
{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  }
}
'''

# 需要填充的部分
additional_data = {
  "phone": "123-456-7890",
  "email": "john@example.com"
}

# 解析原始JSON对象
parsed_json = json.loads(original_json)

# 创建新的JSON对象
new_json = {}

# 复制原始JSON对象的属性到新的JSON对象
for key, value in parsed_json.items():
    new_json[key] = value

# 填充需要的属性
for key, value in additional_data.items():
    new_json[key] = value

# 将新的JSON对象转换为字符串
result_json = json.dumps(new_json)

print(result_json)
