my code seems correct from fiddle but i cant see what it is testing it with

if i could see what is being tested against this code, it would be beneficial in being able to solve as this works in fiddle

sets.py
COURSES = {
    "Python Basics": {"Python", "functions", "variables",
                      "booleans", "integers", "floats",

}

def covers(topics):
    courses_that_cover = []

    for topic in COURSES:
        if COURSES[topic] & topics == topics:
            courses_that_cover.append(topic)

    return courses_that_cover

For this function, you only need to determine if there is any overlap. It's not necessary for the overlap to exactly match the input set.

        if COURSES[topic] & topics:  # check for any overlap

But your concept may come in handy for the next task!
