Ich habe die Datei mit folgendem Code geladen:

import json
with open('./test.json', 'r') as json_file:
    data = json.load(json_file)

Aber es wirft einen Fehler auf : JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1).

Andere Option:

data = json.loads('./test.json')
print(data)

Ausgabe:

JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Wie könnte ich es richtig machen? Vielen Dank im Voraus.

Answer 1

Es gibt 2 Probleme in JSON.

1. Array-Klammern fehlen []
2. Ändern 'in"

Richtiger JSON:

Answer 2

Dies ist keine JSON-Datei. Sieht aus wie ndjson. Schauen Sie sich das Drittanbieterpaket ndjson an

Außerdem sollten doppelte Anführungszeichen und keine einfachen Anführungszeichen verwendet werden.

Wenn dies eine Datei ist, die Sie erstellen oder ändern können, können Sie diese 3 JSON-Objekte in ein JSON-Array einfügen, und dann ist t ein gültiger JSON.

Answer 3

Das Problem ist, dass Ihre Datei kein gültiger JSON ist. Sie benötigen doppelte Anführungszeichen anstelle von einfachen Anführungszeichen um Ihre Zeichenfolgen, und Sie müssen Ihre drei Objekte in ein Array einschließen.

Versuchen Sie stattdessen Folgendes:

[
    {"review/appearance": 2.5, "beer/style": "Hefeweizen", "review/palate": 1.5, "review/taste": 1.5, "beer/name": "Sausa Weizen", "review/timeUnix": 1234817823, "beer/ABV": 5.0, "beer/beerId": "47986", "beer/brewerId": "10325", "review/timeStruct": {"isdst": 0, "mday": 16, "hour": 20, "min": 57, "sec": 3, "mon": 2, "year": 2009, "yday": 47, "wday": 0}, "review/overall": 1.5, "review/text": "A lot of foam. But a lot.\tIn the smell some banana, and then lactic and tart. Not a good start.\tQuite dark orange in color, with a lively carbonation (now visible, under the foam).\tAgain tending to lactic sourness.\tSame for the taste. With some yeast and banana.", "user/profileName": "stcules", "review/aroma": 2.0},
    {"review/appearance": 3.0, "beer/style": "English Strong Ale", "review/palate": 3.0, "review/taste": 3.0, "beer/name": "Red Moon", "review/timeUnix": 1235915097, "beer/ABV": 6.2, "beer/beerId": "48213", "beer/brewerId": "10325", "review/timeStruct": {"isdst": 0, "mday": 1, "hour": 13, "min": 44, "sec": 57, "mon": 3, "year": 2009, "yday": 60, "wday": 6}, "review/overall": 3.0, "review/text": "Dark red color, light beige foam, average.\tIn the smell malt and caramel, not really light.\tAgain malt and caramel in the taste, not bad in the end.\tMaybe a note of honey in teh back, and a light fruitiness.\tAverage body.\tIn the aftertaste a light bitterness, with the malt and red fruit.\tNothing exceptional, but not bad, drinkable beer.", "user/profileName": "stcules", "review/aroma": 2.5},
    {"review/appearance": 3.0, "beer/style": "Foreign / Export Stout", "review/palate": 3.0, "review/taste": 3.0, "beer/name": "Black Horse Black Beer", "review/timeUnix": 1235916604, "beer/ABV": 6.5, "beer/beerId": "48215", "beer/brewerId": "10325", "review/timeStruct": {"isdst": 0, "mday": 1, "hour": 14, "min": 10, "sec": 4, "mon": 3, "year": 2009, "yday": 60, "wday": 6}, "review/overall": 3.0, "review/text": "Almost totally black.

]

Funktioniert übrigens obj = json.loads('./test.json')nicht wie json.loadserwartet eine JSON-Zeichenfolge, kein Dateipfad oder Dateiobjekt. ( loadssteht für "load string".) Sie möchten json.loadstattdessen.

Answer 4

Die Datei ist nicht json. Dies wurde vor gefragt hier

JSON verwendet kein einfaches Anführungszeichen ', sondern doppelte Anführungszeichen"
