Question

我需要将函数getvalues返回的字典添加到“data.update”中我可以添加为单独的json。但无法在字段键中添加它。请检查输出和所需的输出。

这是我写的代码：

import json 
import csv
import glob
import os



csvfile = open('file.csv', 'r')
name = (os.path.splitext('file.csv')[0])
exampleReader = csv.reader(csvfile)
exampleData = list(exampleReader)



def getvalues():
    for row in exampleData[:1]:
        lis = {}
        for r in row:
            lis.update({r:r})
        return lis


data = {}  

data.update({  

  "pattern": name+'.csv',
  "source_args": {
    "encoding": "UTF-16"
  },
  "parser_args": {
    "type": "csv",
    "delimiter": ","
  },
  "outputs": [
    {
      "name": name,
      "fields": {


      }
    }
  ]

})

result =json.dumps(data)
result1 =json.dumps(getvalues())
file = open("data.json","w")
file.write(result)
file.write(result1)

以下是实际输出和所需输出：

#Output : {"pattern": "file.csv", 
            "source_args": 
              {
               "encoding": "UTF-16"
              }, 
             "parser_args": {
                 "type": "csv", 
                 "delimiter": ","
              }, "outputs": 
                   [
                   {
                    "name": "file", 
                    "fields": {}
                    }
            ]}
           {
           "facility_id": "facility_id", 
           "facility_type": "facility_type", 
           "facility_name": "facility_name", 
           "facility_branch": "facility_branch", 
           }
    #Desired Output : {"pattern": "file.csv", 
            "source_args": 
              {
               "encoding": "UTF-16"
              }, 
             "parser_args": {
                 "type": "csv", 
                 "delimiter": ","
              }, "outputs": 
                   [
                   {
                    "name": "file", 
                    "fields": {
                     "facility_id": "facility_id", 
                     "facility_type": "facility_type", 
                     "facility_name": "facility_name", 
                     "facility_branch": "facility_branch", 
                     }
                    }
            ]}

拜托，让我知道如何实现这一目标。

更新：错误
  如果我以下列方式直接添加功能。 fields {getvalues（）} 。我收到以下错误。

Traceback (most recent call last):
  File "chej.py", line 50, in <module>
    getvalues()
TypeError: unhashable type: 'dict'

Answer 1

你可以试试这个：

"outputs": [
{
  "name": name,
  "fields": getvalues()
}

使用python中的函数返回数据写入json文件
