How to check div class="popup__content with selenium + webdriver?

Question

Python

Hello!
How to check the drop-down box in yandex.ru when entering a query in the search? i found its xpath and class but can't check.
The question is that I need to enter a word into the search, then check whether a window has appeared and then perform a search.
What is the algorithm? why can't I check if there is a list or not. and simply says that such a pass does not work or there is no such class. until nothing is entered in the search, the class is inactive

Answer 1

import time

time.sleep(<seconds>) # расставить паузы там где нужно подождать

Wait until the desired element appears in the DOM and selenium will find it. Otherwise an error will occur
