covers_all task 2 of 2

Hello , I am having trouble passing this challenge. this is my code so far 

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):
    final_list = []
    for course_name, course_topic in COURSES.items():
        if course_topic.intersection(topics):
            final_list.append(course_name)
    return final_list

def covers_all(course):
    course_list = []
    for course_name, course_topic in COURSES.items():
        if course_topic.intersection(course):
            course_list.append(course_name)
    return course_list

My logic is to create an empty list. Then go through the dictionary in a loop and basically check if the value is in the function. if it is then append it to the empty list. I know I am missing a step so if anyone can help me that would be great

Hey Omar,

you need to check if your course_name's set of topics is a superset to your course parameter (which is a list of topics):

...
if course_topic >= course:
