如何为所有匹配结果创建单个JSON？

import json

# 获取所有匹配结果的数据
matching_results = [
    {"id": 1, "name": "Result 1", "score": 0.9},
    {"id": 2, "name": "Result 2", "score": 0.8},
    {"id": 3, "name": "Result 3", "score": 0.7}
]

# 创建空的JSON对象
json_data = {}

# 遍历匹配结果并创建JSON对象
results_array = []
for result in matching_results:
    result_json = {
        "id": result["id"],
        "name": result["name"],
        "score": result["score"]
    }
    results_array.append(result_json)

# 将JSON数组添加到JSON对象中
json_data["results"] = results_array

# 将JSON对象转换为字符串
json_string = json.dumps(json_data)

print(json_string)

{
  "results": [
    {
      "id": 1,
      "name": "Result 1",
      "score": 0.9
    },
    {
      "id": 2,
      "name": "Result 2",
      "score": 0.8
    },
    {
      "id": 3,
      "name": "Result 3",
      "score": 0.7
    }
  ]
}
