Hello! I dont know if I dont understand what this code challenge is asking. I don't know whats wrong with my code.

Heres my code

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):
    overlap = []
    for course in COURSES.keys():
        if topics <= COURSES[course]:
            overlap.append(course)
    return overlap

You're really close! Your function structure is good, and it looks like the only issue is when you test for overlap using "<=" as the operator. But this is not one of the set operators introduced in the video.

Take a look at the operator summary in the Teacher's notes at the bottom of the video page and see if you can pick one of the set operators that would be good for detecting an overlap in the sets. I'll bet you can get it on the next try!
