Problem mit verschachtelten Daten in einem Wörterbuch

Question

f = open("sample_flickr_response.json","r") 
search_result_diction = json.loads(f.read()) 
print search_result_diction 
f.close() 
search_result_diction["id"] 
for sample_photo_ids in sample_photo_ids["id"]: 
    print sample_photo_ids['raw'] 

Ich habe einige Probleme mit meinem oben genannten Code. Ich versuche, um die Datei zu öffnen und die Daten innerhalb dieser Datei in eine Variable laden genannt search_result_diction.The Variable search_result_diction enthält einen sehr komplexen Wörterbuch (siehe unten). Jeder Gegenstand hat eine ID. Ich versuche, eine Liste aller Ide von jedem Element zu erstellen, die die search_result_diction Daten darstellt, und in einer Variablen namens sample_photo_ids diese Liste speichern.

Der aktuelle Fehler Ich erhalte eine KeyError: ‚id‘.

unten ist das Wörterbuch für sample_flickr_response.json

Answer 1

Borrowing von @roganjosh's comment, ein idiomatischen Weg, um die id s zu erhalten:

ids = [item["id"] for item in search_result_diction["photos"]["photo"]] 

Ihnen ein list von id s geben, die Sie drucken können dann:

for id in ids: 
    print id 

Ausgang:

33119881551 
32433652893 
33091881772 
... 

In einem for -loop näher an, was Sie in der Frage verwenden, dies wird Ihnen auch das gleiche geben:

for item in search_result_diction["photos"]["photo"]: 
    print item["id"]
