从python中的大型json文件中获取可读文本 [英] Getting readable text from a large json file in python

问题描述

我有一个简单的问题.在 python 中，我得到了一个非常大的字符串，其中包含一些文本，例如:\u0398\u03b5\u03b1\u03c4\u03c1\u03b9\u03ba\u03cc

我需要的只是将其转换为可读文本.我正在寻找其他一些帖子，但没有找到任何解决方案.

尝试了以下操作，但没有成功:

rawtext = str(json.dumps(result, indent=2, sort_keys=True))纯文本 = str(原始文本)with open("result.txt", "a+", encoding="utf-8-sig") as f:f.写(纯文本)

这是来自 result.txt 文件的示例:

解决方案

默认情况下，json 模块会转义所有非 ascii 字符.使用 ensure_ascii=False 保持所有 unicode 字符未转义:

<预><代码>>>>打印(json.dumps("""{"date": "Πριν από 3 ώρες"}"""))"{\"日期\": \"\u03a0\u03c1\u03b9\u03bd \u03b1\u03c0\u03cc 3 \u03ce\u03c1\u03b5\u03c2\"}">>>print(json.dumps("""{"date": "Πριν από 3 ώρες"}""", ensure_ascii=False))"{\"日期\": \"Πριν από 3 ώρες\"}"

在转储数据时只需传递参数:

 with open("result.txt", "a+", encoding="utf-8-sig") as f:json.dump(result, f, indent=2, sort_keys=True)

请注意，就 JSON 标准而言，带有和不带有非 ascii 转义的 JSON 是等效的.

I got an simple question. In python, i got a very large string which got some text like: \u0398\u03b5\u03b1\u03c4\u03c1\u03b9\u03ba\u03cc

All i need, is to convert it into readable text. I was looking in some other posts, but didn't find any solution.

Edit: Tried the following, without any success:

rawtext = str(json.dumps(result, indent=2, sort_keys=True))
puretext = str(rawtext)
with open("result.txt", "a+", encoding="utf-8-sig") as f:
    f.write(puretext)

This is example from the result.txt file:

    {
      "date": "\u03a0\u03c1\u03b9\u03bd \u03b1\u03c0\u03cc 3 \u03ce\u03c1\u03b5\u03c2",

解决方案

By default, the json module escapes all non-ascii characters. Use ensure_ascii=False to keep all unicode characters unescaped:

>>> print(json.dumps("""{"date": "Πριν από 3 ώρες"}"""))
"{\"date\": \"\u03a0\u03c1\u03b9\u03bd \u03b1\u03c0\u03cc 3 \u03ce\u03c1\u03b5\u03c2\"}"
>>> print(json.dumps("""{"date": "Πριν από 3 ώρες"}""", ensure_ascii=False))
"{\"date\": \"Πριν από 3 ώρες\"}"

Simply pass the parameter when dumping your data:

with open("result.txt", "a+", encoding="utf-8-sig") as f:
    json.dump(result, f, indent=2, sort_keys=True)

Note that JSON with and without non-ascii escaping are equivalent as far as the JSON standard is concerned.
