How to search if 2 sets of strings are present in a different string in an if statement?

I want to search for two sets of strings in a string in an if statement but I'm not sure how to do that. As of now this is what I've typed:

description0=(driver.find_element_by_id('vjs-content').text)
    for mark in markerfile:
       if mark in description0.split():

Basically I want to search for mark and mark.swapcase() in description0.split() without adding another for loop.
