sets and dictionaries

I'm kind of confuse on how to use sets on dictionaries, my code wouldn't pass

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(set_of_topics):
    topic = []
    for course,topics in set(COURSES):
        topic.append(course,topics)
    return topic

And by compare I mean find the intersection of the two sets

Hey Mathew, I don't think you want to turn the entire COURSES dict into a set. Notice that the values of the dict are already sets. So, you have to access the values of each key in the dict and compare them with set_of_topics set.
