在Python中，如何通过删除方括号和花括号来打印Json [英] In Python, how to print Json by removing brackets and braces

问题描述

我想以一种不错的方式打印Json，我想摆脱括号，引号和花括号，而仅使用缩进和行尾来显示json的结构。

I want to print the Json in a nice way, I want to get rid of the brackets, quotes and braces and only use indents and line-endings to show the json's structure.

例如，如果我有这样的Json：

for example if I have a Json like this:

    {
        "A": {
            "A1": 1,
            "A2": 2
        },
        "B": {
            "B1": {
                "B11": {
                    "B111": 1,
                    "B112": 2
                },
                "B12": {
                    "B121": 1,
                    "B122": 2
                }
            },
            "B2": {
                "B21": [1,2],
                "B22": [1,2]
            }
        },
        "C": "CC"
    }

我如何通过删除{}和[]来打印json，我想要的是：

How could I print the json by removing {} and [], what I want is:

A:
  A1: 1
  A2: 2
B:
  B1:
     B11:
         B111: 1
         B112: 2
     B12:
         B121: 1
         B122: 2
  B2:
     B21: 1, 2
     B22: 1, 2

推荐答案

您可以将json加载到python对象中，然后将python对象转换为YAML。另一个解决方案是简单地遍历字典并根据需要对其进行格式化。

You can load the json into a python object, and then convert the python object to YAML. The other solution is to simply iterate over the dictionaries and format it however you want.

这里有一个将其转换为YAML的示例。它不能完全满足您的需求，但是非常接近。有很多方法可以自定义输出，这只是一个简单的技巧，可以显示一般的想法：

Here's an example of converting it to YAML. It doesn't give you precisely what you want, but it's pretty close. There are lots of ways to customize the output, this is just a quick hack to show the general idea:

import json
import yaml

data = json.loads('''
   {
        "A": {
            "A1": 1,
            "A2": 2
        },
        "B": {
            "B1": {
                "B11": {
                    "B111": 1,
                    "B112": 2
                },
                "B12": {
                    "B121": 1,
                    "B122": 2
                }
            },
            "B2": {
                "B21": [1,2],
                "B22": [1,2]
            }
        },
        "C": "CC"
    }
''')

print yaml.safe_dump(data, allow_unicode=True, default_flow_style=False)

这是我得到的输出：

A:
  A1: 1
  A2: 2
B:
  B1:
    B11:
      B111: 1
      B112: 2
    B12:
      B121: 1
      B122: 2
  B2:
    B21:
    - 1
    - 2
    B22:
    - 1
    - 2
