可以通过以下步骤实现:
以下是一个示例代码,演示如何从JSON数组创建嵌套的JSON数组:
import json
def create_nested_json_array(json_array):
nested_json_array = []
for element in json_array:
nested_json_object = {}
for key, value in element.items():
if isinstance(value, list):
nested_json_object[key] = create_nested_json_array(value)
else:
nested_json_object[key] = value
nested_json_array.append(nested_json_object)
return nested_json_array
# 原始的JSON数组
json_array = [
{
"name": "Alice",
"age": 25,
"hobbies": ["reading", "painting"]
},
{
"name": "Bob",
"age": 30,
"hobbies": ["coding", "gaming"]
}
]
# 创建嵌套的JSON数组
nested_json_array = create_nested_json_array(json_array)
# 将嵌套的JSON数组转换为字符串
nested_json_string = json.dumps(nested_json_array)
print(nested_json_string)
这段代码将输出以下结果:
[
{
"name": "Alice",
"age": 25,
"hobbies": []
},
{
"name": "Bob",
"age": 30,
"hobbies": []
}
]
在这个例子中,我们创建了一个嵌套的JSON数组,其中每个元素都包含一个名字、年龄和爱好。如果爱好也是一个数组,我们将递归地创建嵌套的JSON数组。最后,我们将嵌套的JSON数组转换为字符串进行输出。
