What's wrong with this implementation?

I guess i don't understand the question!

sets.py
COURSES = {

                      "booleans", "integers", "floats",
                      "arrays", "strings", "exceptions",

    course_list = []
    for course_name, course_value in COURSES.items():
        if topics.issubset(course_value):
            course_list.append(course_name)

You are almost there. I have just modified the if statement headline to compare if the topics provided is within the list (inclusive). It works..and here is the code: def covers(topics): course_list = [] for course_name, course_value in COURSES.items(): if course_value & topics: #this line is the modification i made :) course_list.append(course_name) return course_list

I'd figured it out . Thanks Ebenezer :)
