Question

我正在尝试使用python构建一个JSON文件，并从CSV文件开始。

CSV文件如下所示：

a,b,tableau.c,tableau2.d,tableau2.e,tableau2.f,tableau2.g,tableau.h
11725,11741,false,N/A,true,23,N/A,false

到目前为止，我正在设法将csv文件转换为JSON文件，并将其排列如下：

[
  {
    "a": "11725",
    "b": "11741",
    "tableau.c": "false",
    "tableau.h": "false",
    "tableau2.d": "N/A",
    "tableau2.e": "true",
    "tableau2.f": "23",
    "tableau2.g": "N/A"
  }
]

使用此代码：

import csv
import json

file = "myFile.csv"
json_file = "myFile.json"
csv_rows = []

with open(file) as csvfile:
    reader = csv.DictReader(csvfile)
    title = reader.fieldnames

    for row in reader:
        csv_rows.extend([{title[i]:row[title[i]] for i in     range(len(title))}])


with open(json_file, "w") as f:
    f.write(json.dumps(csv_rows, sort_keys=True, indent=4, separators=(',', ': ')))

但是我希望得到一个看起来像这样的JSON文件：

[
    {
        "a": "11725",
        "b": "11741",
        "tableau": [
        { 
          "value" :"false",
          "name" : "c"
        },
        { 
          "value" :"false",
          "name" : "h"
        },
    ]
        "tableau2": [
        { 
          "value" :"N/A",
          "name" : "d"
        },
        { 
          "value" :"true",
          "name" : "e"
        },
        { 
          "value" :"23",
          "name" : "f"
        },
        { 
          "value" :"N/A",
          "name" : "g"
        },
    ]

    }
]

我一直在寻找有关如何做到这一点的答案，到目前为止一无所获。

有关如何执行此操作的任何建议吗？

提前谢谢

这有效：

for row in reader:
    row_result = {}
    for key, value in row.iteritems():
        if '.' in key:
            tableau, name = key.split('.')
            row_result.setdefault(tableau, []).append({'value': value, 'name': name})
        else:
            row_result[key] = value
    csv_rows.append(row_result)
