Question

一个新手。我正在尝试锻炼应该如何从执行特定boto3方法时产生的json输出中提取一些特定值。下面是有效的代码；

import json
import boto3

def lambda_handler(event, context):

    client = boto3.client('apigateway')
    response = client.get_usage_plans()['items']
    return response

上面给出了我预期的以下输出。

Response:
[
  {
    "id": "p90xvt",
    "name": "Basic",
    "apiStages": [
      {
        "apiId": "g1gckiw2cj",
        "stage": "prod"
      }
    ],
    "quota": {
      "limit": 10,
      "offset": 0,
      "period": "DAY"
    }
  },
  {
    "id": "rt9k2q",
    "name": "Prem",
    "apiStages": [
      {
        "apiId": "g1gckiw2cj",
        "stage": "prod"
      }
    ],
    "quota": {
      "limit": 10,
      "offset": 0,
      "period": "DAY"
    }
  }
]

我想了解的是如何从输出中提取一些特定的key：values？说，如果配额限制属于特定ID（即“ p90xvt”）等于10，是否要打印YES？请注意，我需要掩盖所有ID。

非常感谢您对这个人的帮助。提前谢谢了。 -B

 for field in response:
        if field['quota']['limit']==10:
            print (field['id'])
