İşte selenyum ile amazon aramaları için bir kuyruk sağlamak için bazı zaman uyumsuz kodlar, neden AttributeError alıyorum? _ _ init _ _ çalışmıyor mu?

Soru

İşte Amazon'u tornado web uygulamamdan aramak için kullandığım kod. Şu anda yalnızca bu sınıflardan birinin (ve bir webdriver) örneği var. Gelecekte onlardan bir havuz isteyebilirim (evet selenum ızgarası olduğunu biliyorum, ama bu benim sorum değil.) Sorum şu, neden__ init _ _ görünüşte çalışmıyor? Neden kendine erişmek için bir attributeError var.__init__ ' de açıkça tanımlanmış olan kuyruk var mı?

İşte hata:

Traceback (most recent call last):

    print(asyncio.run(a.search("test")))

Rediciulous nasıl... __init__ işlevini __init___olarak adlandırmıştım.

Diğer hataları düzelttim ve işte çalışma kodu
