I am getting the expected output but the code challenge is rejecting my code. What am I doing wrong?

I've tested against..

print(type(covers({"floats", "Python"}))) print(covers({"floats", "Python"})) print(covers({"floats", "strings"}))

sets.py 
COURSES = {
    "Python Basics": {"Python", "functions", "variables",
                      "booleans", "integers", "floats",
                      "arrays", "strings", "exceptions",
                      "conditions", "input", "loops"},
    "Java Basics": {"Java", "strings", "variables",
                    "input", "exceptions", "integers",
                    "booleans", "loops"},
    "PHP Basics": {"PHP", "variables", "conditions",
                   "integers", "floats", "strings",
                   "booleans", "HTML"},
    "Ruby Basics": {"Ruby", "strings", "floats",
                    "integers", "conditions",
                    "functions", "input"}
}

def covers(topics):
    match_list = []
    for course in COURSES:
        compare = set(COURSES.get(course))
        if topics < compare:
            match_list += [course]

    return match_list

I found the answer in other questions. After writing this question I found where challenge questions are... It appears the question is looking for a single overlap and not all of them. Subset would require the whole set to be an intersection and intersection only requires one value to return true.
