Getting readable text from a large json file in python

问题

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",

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.
