This one I researched when I had a page to test that had Previous/Next pagination buttons disabled if less than a certain number of rows were shown.
It went something like this:
if self.driver.find_element_by_id(TheMostAwesomeReport.nextButton).is_enabled():
#Test pagination scenario
else:
#pass or continue, or some other check here
This was for an input element that did have the disabled attribute:
disabled="disabled"
Definitely helpful.
