Использование Python, как я могу вернуть JSON-файл после выполнения функций на нем и преобразования его в словарь?

Question

В настоящее время я работаю с данными netflow в json-файле. Моя задача - проанализировать json-файл и выполнить определенные действия над данными внутри него. После этого я создаю новый файл и добавляю к нему каждый новый обновленный json-объект. Что происходит, так это то, что все они находятся на одной линии. Есть ли способ получить каждый объект/строку json на другую строку? Оригинальный файл, предоставленный мне, тоже был таким, и он просто выглядит аккуратно. Благодаря!

EDIT:

Что я хочу:

Что происходит в настоящее время: Вместо того, чтобы быть на отдельных строках, каждый объект JSON как раз после того, как другой (так что это одна большая линия, когда ты откройте его, чтобы прочитать его). Я хочу, чтобы он был отделен по строкам, как показано выше. Я бы показал текущий результат, но я шел по своему лимиту.

Надеюсь, это поможет!

Answer 1

Трудно точно знать, какова ваша проблема без вашего кода, но я думаю, вы хотите использовать json.dumps.

Пример использования из документации:

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

В вашем примере, это будет выглядеть примерно так:

data = [{"@timestamp":"2015-05-18T19:26:13.000Z","netflow":{"version":"9"}},{"@timestamp":"2015-05-18T19:26:13.000Z","netflow":{"version":"9"}}] 

with open("test.json", "w"): 
    json.dumps(data, indent=1) 

# test.json 
[ 
{ 
    "@timestamp": "2015-05-18T19:26:13.000Z", 
    "netflow": { 
    "version": "9" 
    } 
}, 
{ 
    "@timestamp": "2015-05-18T19:26:13.000Z", 
    "netflow": { 
    "version": "9" 
    } 
} 
] 

EDIT: Если вы хотите, чтобы каждый JSON-объект на своей собственной линии, вы мог бы использовать:

with open("test.json", "w+") as f: 
    for line in data: 
     f.write(str(line) + "\n") 

#test.json 
{'@timestamp': '2015-05-18T19:26:13.000Z', 'netflow': {'version': '9'}} 
{'@timestamp': '2015-05-18T19:26:13.000Z', 'netflow': {'version': '9'}} 

Обратите внимание, что это недействительно json, поскольку они должны быть в массиве. Возможно, вы также захотите заменить ' -вопросами " -quotes. Это можно сделать с помощью .replace("'", '"')

Вы можете использовать довольно-печатную библиотеку.

import pprint 

beautify = {"@timestamp":"2015-05-18T19:26:13.000Z......."} #Your Input 
pp = pprint.PrettyPrinter(indent=4) 
pp.pprint(beautify)
