如何使用 python 和 watson discovery news 从 JSON 中查找数据

Question

{
  "matching_results": 1264,
  "results": [
    {
      "main_image_url": "https://s4.reutersmedia.net/resources_v2/images/rcom-default.png",
      "enriched_text": {
        "entities": [
          {
            "relevance": 0.33,
            "disambiguation": {
              "subtype": [
                "Country"
              ]
            },
            "sentiment": {
              "score": 0
            },
            "type": "Location",
            "count": 1,
            "text": "China"
          },
          {
            "relevance": 0.33,
            "disambiguation": {
              "subtype": [
                "Country"
              ]
            },
            "sentiment": {
              "score": 0
            },

这个文件太大了，所以我想用 python.
找到 "relevance" 和 "score" 如何获取此信息？

Answer 1

不管它有多大，也只是一本简单的字典。

迭代列表。提取键值。

for result in data['results']:
    for e in result['enriched_text']['entities']:
        print(e['relevance'])
        print(e['sentiment']['score'])
