在Python中用多列組成嵌套JSON

Question

我有一個csv文件，並嘗試從中撰寫JSON。 文件中有多條記錄，但我在這里僅給出一組示例記錄。此結構由claimID驅動。 在ClaimLineDetail和ClaimSpecDiag上有嵌套。我想我必須創建某種列表來處理此問題，然后問題是如何將其附加到所需的結構中。 我確實需要一些指導才能達到預期的效果。 我不確定只是假設，因為有多個列，所以可以細分不同的部分並在以后追加。

代碼：

import csv,json

data = []
with open('JsonRequestPricingMedical.csv','r') as f:
    reader = csv.DictReader(f)
    for row in reader:
        print row

csv文件：

claimId,subscriberId,claimType,claimSubType,providerId,totalChargeAmt,claimLineNo,pos_code,procedureCode,subdiagnosisCode,svcLineFromDt,svcLineToDt,chargedAmt,clmLineUnits,presentOnAdmit,diagnosisCode
18A000730400,101924200,M,M,002664514003,585,1,11,92014,H43393,2017-06-19,2017-06-19,160,1,U,H43393
18A000730400,101924200,M,M,002664514003,585,2,12,92015,H43395,2017-06-19,2017-06-19,160,2,U,H43394

所需的JSON

[

   "claimsHeader":" {
    "claimId": "18A000730400",
    "subscriberId": "101924200",

                },

                },

     "totalChargeAmt": "585",
     "claimLineDetail" :[

                "svcLineFromDt": "2017-06-19",
                "svcLineToDt": "2017-06-19",
                "chargedAmt": "160",
                "clmLineUnits": "1",
                },

                },
                "subDiagnosisCd": {
                        "code": "H433945
                },
                "svcLineFromDt": "2017-06-19",
                "svcLineToDt": "2017-06-19",
                "chargedAmt": "160",
                "clmLineUnits": "2",
                }
     ],
     {
        "claimSpecDiag": [

            "presentOnAdmit": "",
            "diagnosisCode": "H43393",

         },
         {
            "presentOnAdmit": "",
            "diagnosisCode": "H43394",
         }

    ]   
  }
]

Answer 1

讀取csv時，每一行代表由特殊字符分隔的變量，在本例中為逗號：“，”。

您可以通過執行line_variables = row.split(',')分離每個變量

只需通過第一行，對於其他所有代碼，請執行以下操作：

result = {
   "claimsHeader":" {
    "claimId": line_variables[0],
    "subscriberId": line_variables[1],
    "claimType":{
        "code": line_variables[2]
    }
...

最后，只需將結果添加到帶有your_list.append(result)的列表（在for循環之前創建your_list.append(result) 。
