在python中从JSON字典中搜索并获取值

试试这个-

import json
json_data = """{
            "countries": [],
            "companies": [
                {
                    "guid": "49d01ed7-4285-4bed-a602-0e3bbdc179a1",
                    "custom_id": null,
                    "name": "Creavath, Sweaine & Mare LTD",
                    "shortname": "Creavath",
                    "href": "https://api.com/ratings/v1/companies/49d01ed7-4285-4bed-a602-0e3bbdc179a1"
                },
                {
                    "guid": "edade1ed-9e08-4bc0-bc24-5d05c7903c53",
                    "custom_id": null,
                    "name": "Kremar Levin Natlis & Franklin LTD",
                    "shortname": "Kremar Levin",
                    "href": "https://api.com/ratings/v1/companies/edade1ed-9e08-4bc0-bc24-5d05c7903c53"
                }
            ]
       }"""
parsed_json = json.loads(json_data)

如果json文件中有json(扩展名为.json),请使用--

with open('jsonfile.json', 'r') as f:
    parsed_json = json.load(f)

之后,使用下面的代码获取name或short name的guid-

user_input = 'Creavath' # for example, user gives this input

for company in parsed_json['companies']:
    if company['name'] == user_input or company['shortname'] == user_input:
        print(company['guid'])
        break
