Python Selenium Why can't find div?

Question

Python

Prior to that, it calmly finds elements by id and class
. But at this moment there is an error:
elem=driver.find_element_by_id('730_2_8695061953')

Traceback (most recent call last):
  File "main.py", line 30, in <module>
    elem=driver.find_element_by_id('730_2_8695061953')
  File "/Users/kosyachniy/anaconda/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 289, in find_element_by_id

This is what the site looks like (copied from the one launched by the application itself):

<div class="item app730 context2" id="730_2_8695061953" style="border-color: rgb(210, 210, 210);">
<img src="http://community.edgecast.steamstatic.com/economy/image/-9a81dlWLwJ2UUGcVs_nsVtzdOEdtWwKGZZLQHTxDZ7I56KU0Zwwo4NUX4oFJZEHLbXH5ApeO4YmlhxYQknCRvCo04DEVlxkKgpouLWzKjhzw8zFdC5K092kl5SClMj3PLXFhGpC_Pp8j-3I4IG7i1Hn_UI-Nmj3ItDGe1BoN1mCr1G4xL_vhMS8tcmcn3JhuihwsHvbzQv3309k3tBw8A/96fx96fdpx2x">
<a href="#730_2_8695061953" class="inventory_item_link"></a></div>

I need to click on it, but it can't even find it

Answer 1

the element may not have time to load before it is searched.

Answer 2

Maybe an element inside an iframe
