التكرار من خلال JSON المتداخل المستلم من بيانات واجهة برمجة التطبيقات التي لا تعمل

1

لقد جربت كل طريقة ، ونظرت إلى كل فيديو ، وجوبت Stack Overflow للبحث عن حلول. يبدو أن لا شيء يعمل. هدفي هو إنشاء قائمة بالبيانات الأولية فقط. مثال على الإخراج المثالي: [date1, data1a, data1b, data1c, data1d, data1f, date2, data2a, data2b, etc,] مقدار الوقت الذي قضيته في شيء من المفترض أنه تافه جعلني مرتبكًا تمامًا. يجب أن يكون هناك شيء أفتقده.

فيما يلي البيانات إذا تمت طباعتها للتو بعد استردادها.

هناك مشكلتان تواجههما هنا:

المشكلة رقم 1 هي أن البيانات التي تقوم بتحليلها ليست في الواقع مفتاحًا: زوج كائن القيمة كما يوحي الكود الخاص بك أنك تتوقع ؛ إنها في الواقع مجموعة من الصفوف. لماذا ا؟ دونو - بالتأكيد ليس تصميم واجهة برمجة التطبيقات الأكثر أناقة.

المشكلة رقم 2 لأن هذه المشكلة ، والتي تم حلها باستخدام .iteritems() (أو .items() لبيثون 3) .

جرب هذا:

for o in data.iteritems():
    for date, data in {o[0]: o[1]}.iteritems():
        print(date, data['1. open'], data['2. high'], ....etc.)
