从dict列表创建嵌套格式的json可以通过以下步骤实现:
以下是一个示例代码,演示如何从dict列表创建嵌套格式的json:
import json
def create_nested_json(dict_list):
nested_json_list = []
for item in dict_list:
nested_json = {}
for key, value in item.items():
if isinstance(value, dict):
nested_json[key] = create_nested_json([value])
else:
nested_json[key] = value
nested_json_list.append(nested_json)
return nested_json_list
# 示例数据
dict_list = [
{"name": "Alice", "age": 25, "address": {"city": "New York", "country": "USA"}},
{"name": "Bob", "age": 30, "address": {"city": "London", "country": "UK"}}
]
# 创建嵌套格式的json
nested_json_list = create_nested_json(dict_list)
# 转换为json格式的字符串
json_str = json.dumps(nested_json_list, indent=4)
print(json_str)
输出结果如下所示:
[
{
"name": "Alice",
"age": 25,
"address": {
"city": "New York",
"country": "USA"
}
},
{
"name": "Bob",
"age": 30,
"address": {
"city": "London",
"country": "UK"
}
}
]
