python - 如何相印JSON文件？(How to prettyprint a JSON file?)

Question

I have a JSON file that is a mess that I want to prettyprint-- what's the easiest way to do this in python?

(我有一个JSON文件是一个混乱，我想漂亮 - 在python中最简单的方法是什么？)

I know PrettyPrint takes an "object", which I think can be a file, but I don't know how to pass a file in-- just using the filename doesn't work.

(我知道PrettyPrint带有一个“对象”，我认为它可以是一个文件，但我不知道如何传入文件 - 只是使用文件名不起作用。)

The json module already implements some basic pretty printing with the indent parameter:

(json模块已经使用indent参数实现了一些基本的漂亮打印：)

>>> import json
>>>
>>> your_json = '["foo", {"bar":["baz", null, 1.0, 2]}]'
>>> parsed = json.loads(your_json)
>>> print(json.dumps(parsed, indent=4, sort_keys=True))
[
    "foo", 
    {
        "bar": [
            "baz", 
            null, 
            1.0, 
            2
        ]
    }
]

To parse a file, use json.load() :

(要解析文件，请使用json.load() ：)

with open('filename.txt', 'r') as handle:
    parsed = json.load(handle)
