twittern Ich versuche twitter Daten iterieren, die in einer JSON-Datei gespeichert ist:JSONDecodeError wenn Iterieren Daten

fname = 'test.json' 

with open(fname, 'r') as f: 
    for line in f: 
     tweet = json.loads(line)['text'] 
     print(tweet)

Es druckt die erste tweet in der Datei nur gut, aber wenn es ein zweites Mal durchläuft es gibt mir ein JSONDecodeError:

JSONDecodeError: Expecting value: line 2 column 1 (char 1)

Meine JSON-Datei ist ungefähr Größe 650Mb ist.

Um die Twitter-Daten zu erhalten, habe ich den StreamListener von der Twitter API verwendet.

Hier ist ein Blick in meine JSON-Datei:

Wie kann ich dieses Problem lösen?

Wenn Ihre JSON-Datei genau die gleiche Struktur wie das Stück hat, das Sie posten, verursachen die leeren Zeilen zwischen Tweets tatsächlich eine JSONDecodeError. Wenn das das Problem ist, überprüfen Sie einfach, dass die Zeile vor der Verarbeitung nicht leer ist:

In [12]: 

with open(fname, 'r') as f: 
    for line in f: 
     if (not line.strip()): 
      continue 
     tweet = json.loads(line)['text'] 
     print(tweet)

Ich hoffe, es hilft.
