Great work! OK, let's create something a bit more refined. Create a new function named covers_all that takes a single s

i am lost in this one

H Mamadou,

The solution I used for the second part checks that both sets have the same values.

it's quite similar to the first task but also checking to see if the intersection set is identical to the argument set

def covers_all(arg):
    course_list = []
    for key, value in COURSES.items():
        if (arg & value) == arg:
            course_list.append(key)
    return course_list 

Hope this helps
