將管道分隔的CSV文件轉換為某種格式的JSON文件

Question

我正在嘗試將CS​​V文件的每一行都轉換為JSON格式。

當我將其轉換為JSON時，它在開頭和結尾都包含方括號，如何將其省略？ 我也在尋找一種將管道值拆分成單獨愛好列表的方法。

這是我得到的輸出：

[
  {
    "Name": "John",
    "Age": "23",
    "Hobby": "Kayaking|Football",
    "Location": "Miami",
    "Profession": "Sales",
  },
  {
    "Name": "Peter",
    "Age": "35",
    "Hobby": "Football|Basketball|Swimming",
    "Location": "Turin",
    "Profession": "Mechanic",
  },
  {
    "Name": "James",
    "Age": "50",
    "Hobby": "Golf",
    "Location": "Berlin",
    "Profession": "Accountant",
  }
]

我想要的輸出

  {
    "Name": "John",
    "Age": "23",
    "Hobby": ["Kayaking","Football"],
    "Location": "Miami",
    "Profession": "Sales",
  },
  {
    "Name": "Peter",
    "Age": "35",
    "Hobby": ["Football","Basketball","Swimming"],
    "Location": "Turin",
    "Profession": "Mechanic",
  },
  {
    "Name": "James",
    "Age": "50",
    "Hobby": "Golf",
    "Location": "Berlin",
    "Profession": "Accountant",
  }

我的代碼：

import glob
import os
import csv
import json


if __name__ == '__main__':
    csv.register_dialect('piper', delimiter='|', quoting=csv.QUOTE_NONE)
    for filename in glob.glob('path_to_csv\file.csv'):
        csvfile = os.path.splitext(filename)[0]
        jsonfile = 'jsfile.json'
        fieldnames = ("Name","Age","Hobby","Location", "Profession")
    with open(csvfile+'.csv') as f:
        reader = csv.DictReader(f,fieldnames)#, dialect='piper')
        rows = list(reader)


    with open(jsonfile, 'w') as f:
        json.dump(rows, f, sort_keys=True, indent=2, separators=(',', ': '))
        f.write('\n')

Answer 1

rows = list(reader)

由於它已經是列表，因此無需將其包裝到列表中。 刪除此線將固定支架。

for row in reader:
   row['Hobby'] = list(row['Hobby'].split('|'))

我們需要拆分愛好字符串並將其轉換為列表
