Hallo, ich habe folgendes json:Wie zu überwinden, das folgende Problem beim Parsen einer JSON-Datei?
j = """[

Da ich brauche eine spezifische Struktur ich es zu analysieren versucht, wie folgt:
js = json.loads(j)
df = pd.concat({i: pd.DataFrame(j) for i, j in enumerate(js)})
df.created = pd.to_datetime(df.created)
df.assign(qna=np.where(df['from'] == 'Bank', 'Answer', 'Question')).set_index(['created', 'qna']).message.unstack(fill_value='')
Alles ist bis zu diesem Zeitpunkt in Ordnung, aber wenn ich hinzufügen, ein anderes Feld mit ich wiederholte Datum bekam folgende Fehlermeldung:
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)

69 df['from'] = df['from'].str.strip()

ich mit diesem neuen json bin versucht, aber es wird von dem Zeitpunkt versagt, so möchte ich recei zu ve unterstützen, diese Aufgabe zu bewältigen:

Nur meine Antwort bearbeitet. Es ist nicht notwendig, "append = True" zu haben. Das Problem bestand darin, dass die Anweisung assign eine eigene Zeile benötigte. –
