I get the correct answer on the python shell on my computer, but, the wrong answer on the coding challenge. :/

I believe I have correctly unpacked, and in implemented the intersection and equivalence operators, so, what could I have possibly done wrong?

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):
    listOfCourses = []
    for course, topicsSet in COURSES.items():
        if ( ( topics & topicsSet ) == topics ):
            listOfCourses.append(course)

    return listOfCourses

You don't need your qualifiers of topics & topicsSet to equal topics. Try just asking if topics& topicsSet: Also, else: continue.
