文本文件到 JSON

Question

我正在尝试将文件中的字符串列表转换为某种 JSON 数据格式。我的 sample.txt 文件包含以下数据：

我想把它转换成下面的形式formated.json:

{
  "x": "1234",
  "y": "a"
},
{
  "x": "5678",
  "y": "a"
},
{
  "x": "9765",
  "y": "a"
}

这是我的代码：

import itertools
import json

with open('sample.txt', 'r') as f_in, open('formated.json', 'w') as f_out:
    for x, y in itertools.zip_longest(*[f_in]*2):
        record = {
            "x": x.strip(),
            "y": "a",
        }
        f_out.write(json.dumps(record, indent=2))
        f_out.write(',\n')

此脚本如何从文本文件跳转每一行并输出：

 {
      "x": "1234",
      "y": "a"
    },
    {
      "x": "9765",
      "y": "a"
    }

但是，我希望我的脚本读取所有行并输出结果。

只使用行内容，不要使用zip:

import json

result = []
with open('sample.txt', 'r') as f_in:
    for line in f_in:
        line = line.strip()
        if not line:
            continue  # skip empty lines

        result.append({'x': line, 'y': 'a'})

with open('formated.json', 'w') as f_out:
    print(json.dumps(result, indent=2))
    #f_out.write(json.dumps(result, indent=2))

输出：

[
  {
    "x": "1234",
    "y": "a"
  },
  {
    "x": "5678",
    "y": "a"
  },
  {
    "x": "9765",
    "y": "a"
  }
]
