【问题描述】：

我需要使用 Python 来解析 JSON 文件的帮助。我使用了一个 API 来获取特定州的立法者列表，我想遍历并找到一个特定的立法者（给定姓氏）。然后我想提取他们的 CID。该文件看起来像这样 `

{
    "response": {
        "legislator": [
            {
                "@attributes": {
                    "cid": "N00029147",
                    "firstlast": "Andy Harris",
                    "lastname": "Harris",
                    "party": "R",
                    "office": "MD01",
                    "gender": "M",
                    "first_elected": "2010",
                    "exit_code": "0",
                    "comments": "",
                    "phone": "202-225-5311",
                    "fax": "202-225-0254",
                    "website": "http://harris.house.gov",
                    "webform": "https://harris.house.gov/contact-me/email-me",
                    "congress_office": "1533 Longworth House Office Building",
                    "bioguide_id": "H001052",
                    "votesmart_id": "19157",
                    "feccandid": "H8MD01094",
                    "twitter_id": "RepAndyHarrisMD",
                    "youtube_url": "https://youtube.com/RepAndyHarris",
                    "facebook_id": "AndyHarrisMD",
                    "birthdate": "1957-01-25"
                }
            },
            {
                "@attributes": {
                    "cid": "N00025482",
                    "firstlast": "Dutch Ruppersberger",
                    "lastname": "Ruppersberger",
                    "party": "D",
                    "office": "MD02",
                    "gender": "M",
                    "first_elected": "2002",
                    "exit_code": "0",
                    "comments": "",
                    "phone": "202-225-3061",
                    "fax": "202-225-3094",
                    "website": "http://ruppersberger.house.gov",
                    "webform": "http://ruppersberger.house.gov/contact-dutch/email-dutch",
                    "congress_office": "2416 Rayburn House Office Building",
                    "bioguide_id": "R000576",
                    "votesmart_id": "36130",
                    "feccandid": "H2MD02160",
                    "twitter_id": "Call_Me_Dutch",
                    "youtube_url": "https://youtube.com/ruppersberger",
                    "facebook_id": "184756771570504",
                    "birthdate": "1946-01-31"
                }
            }

我试图制作一个 for 循环来解析这些值，但它不起作用。（BTW finance info 是 API 给出的数据）。 `


finance_response_info = json.loads(financeInfo)
for v in finance_response_info["response"]:
    for a in finance_response_info["legislator"]:
        for b in finance_response_info["@attributes"][0]:
            if (b["lastname"] == lastName):
        candidateID = b["cid"]

但是，这不起作用，我不断收到错误。我怎样才能正确解析这个？

【解决方案1】：

# Go inside each dict inside the list
for legislator in finance_response_info['response']['legislator']:

    # If the lastname attribute inside the @attributes dict is equal to desired lastname
    if legislator['@attributes']['lastname'] == lastName:
        candidateID = b["cid"]
