How to find the id of an element on the site?

Question

Python

Let's say I have a div. I go to the site through selenium, I find this div by ID. How can I get the date parameter from this div?
<div id="justdiv" data="214345">.......</div>

Answer 1

Everything is done, most likely went a detour and an incredibly long way.
Through selenium, I prescribed a unique property for this diva.
And I parsed the entire text of the page as plain text, then found this element and got the date from it.

Answer 2

So you haven't tried it?
<найденный элемент>.get_attribute('data')
