¿Cómo embellecer JSON en Python?

99

¿Alguien puede sugerir cómo puedo embellecer JSON en Python o mediante la línea de comandos?

El único embellecedor JSON en línea que podía hacerlo era: http://jsonviewer.stack.hu/ .

Sin embargo, necesito usarlo desde Python.

Este es mi conjunto de datos:

{ "head": {"vars": [ "address" , "description" ,"listprice" ]} , "results": { "bindings": [ 
    {
        "address" : { "type":"string", "value" : " Dyne Road, London NW6"},
            "description" :{ "type":"string", "value" : "6 bed semi detached house"},
            "listprice" : { "type":"string", "value" : "1,150,000"}
    }
    ,

Me encanta el título de la pregunta (embellecer) :)

Desde la línea de comandos:

echo '{"one":1,"two":2}' | python -mjson.tool

que salidas:

{
    "one": 1, 
    "two": 2
}

Programmáticamente, el manual de Python describe JSON de impresión bonita :

>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
    "4": 5,
    "6": 7
}

Utilice el indentargumento de la dumpsfunción en el módulo json .

De los documentos:

>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
    "4": 5,
    "6": 7
}

Una solución mínima en Python que colorea los datos json proporcionados a través de la línea de comando:

import sys
import json
from pygments import highlight, lexers, formatters

formatted_json = json.dumps(json.loads(sys.argv[1]), indent=4)
colorful_json = highlight(unicode(formatted_json, 'UTF-8'), lexers.JsonLexer(), formatters.TerminalFormatter())
print(colorful_json)

Inspirado por lo pjsonmencionado anteriormente. Este código debe pygmentsinstalarse.

Ejemplo de salida:

Muy útil. Exactamente lo que estaba buscando: embellecer las salidas de datos JSON en ipython. Gracias.

La mejor respuesta aquí, también incluye una línea usando json.dumps () Usándola con aiohttp en python3.7, no necesitaba usar el módulo sys y unicode (String, encoding). Básicamente se convierte en == highlight (formatted_json, lexers.JsonLexer (), formatters.TerminalFormatter ())

con Python3, solo necesitaba eliminar la llamada unicode () ya que las cadenas son Unicode por defecto en Python3.

Pruebe el subrayado-cli :

cat myfile.json | underscore print --color

Es una herramienta bastante ingeniosa que puede manipular con elegancia muchos datos estructurados, ejecutar fragmentos js, rellenar plantillas, etc. Está ridículamente bien documentado, pulido y listo para un uso serio. Y lo escribí. :)

El comando cli que he usado con Python para esto es:

cat myfile.json | python -mjson.tool

Debería poder encontrar más información aquí:

http://docs.python.org/library/json.html

Ese es otro ejemplo desafortunado de abuso felino. Se puede lograr el mismo resultado sin crear un proceso separado y un montón de copias de memoria gratuitas con un simplepython -mjson.tool < myfile.json

Parece que jsbeautifier abrió sus herramientas y las empaquetó como libs Python y JS, y como herramientas CLI. No parece que llamen a un servicio web, pero no lo revisé demasiado de cerca. Consulte el repositorio de github con las instrucciones de instalación.

De sus documentos para el uso de la biblioteca y la CLI de Python:

Para embellecer usando Python:

$ pip install jsbeautifier
$ js-beautify file.js

La salida embellecida va a stdout.

Usar jsbeautifiercomo biblioteca es simple:

import jsbeautifier
res = jsbeautifier.beautify('your javascript string')
res = jsbeautifier.beautify_file('some_file.js')

... o, para especificar algunas opciones:

opts = jsbeautifier.default_options()
opts.indent_size = 2
res = jsbeautifier.beautify('some javascript', opts)

Si desea pasar una cadena en lugar de un nombre de archivo, y está usando bash, entonces puede usar la sustitución de procesos así:

$ js-beautify <(echo '{"some": "json"}')

No me gustó la salida de json.dumps (...) -> Para mi gusto, demasiadas líneas nuevas. Y no quería usar una herramienta de línea de comandos o instalar algo. Finalmente encontré Pythons pprint (= pretty print). Desafortunadamente, no genera JSON adecuado, pero creo que es útil tener un glympse fácil de usar en los datos almacenados.

Salida de json.dumps(json_dict, indent=4)

{
    "hyperspace": {
        "constraints": [],
        "design": [
            [
                "windFarm.windparkSize.k",
                "continuous",
                [
                    0,
                    0,
                    5
                ]
            ],
            [
                "hydroPlant.primaryControlMax",
                "continuous",
                [
                    100,
                    300
                ]
            ]
        ],
        "kpis": [
            "frequency.y",
            "city.load.p[2]"
        ]
    },
    "lhc_size": 10,
    "number_of_runs": 10
}

Uso de pprint:

import pprint

json_dict = {"hyperspace": {"constraints": [], "design": [["windFarm.windparkSize.k", "continuous", [0, 0, 5]], ["hydroPlant.primaryControlMax", "continuous", [100, 300]]], "kpis": ["frequency.y", "city.load.p[2]"]}, "lhc_size": 10, "number_of_runs": 10}

formatted_json_str = pprint.pformat(json_dict)
print(formatted_json_str)
pprint.pprint(json_dict)

Resultado de pprint.pformat(...)o pprint.pprint(...):

{'hyperspace': {'constraints': [],
                'design': [['windFarm.windparkSize.k', 'continuous', [0, 0, 5]],
                           ['hydroPlant.primaryControlMax',
                            'continuous',
                            [100, 300]]],
                'kpis': ['frequency.y', 'city.load.p[2]']},
 'lhc_size': 10,
 'number_of_runs': 10}

alias jsonp='pbpaste | python -m json.tool'

Esto imprimirá bastante JSON que está en el portapapeles en OSX. Simplemente cópielo y luego llame al alias desde un indicador de Bash.

Puede canalizar la salida a jq. Si su secuencia de comandos de Python contiene algo como

print json.dumps(data)

entonces puedes disparar:

python foo.py | jq '.'

jq es una gran herramienta.

Primero instale pygments

luego

echo '<some json>' | python -m json.tool | pygmentize -l json

Tus datos están mal formados. Los campos de valor, en particular, tienen numerosos espacios y nuevas líneas. Los formateadores automáticos no funcionarán en esto, ya que no modificarán los datos reales. A medida que genera los datos para la salida, fíltrelos según sea necesario para evitar los espacios.

Con jsonlint (como xmllint):

aptitude install python-demjson
