Python Python Collections (2016, retired 2019) Sets Set Math

What is wrong with my code please?

Please see screenshot:

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):
    list_of_courses = []
    for key, value in courses.items():
        if set_of_topics.intersection(value):
            list_of_courses.append(key)
    return list_of_courses

The question is: write a function named covers that accepts a single parameter, a set of topics. Have the function return a list of courses from COURSES where the supplied set and the course's value (also a set) overlap.

For example, covers({"Python"}) would return ["Python Basics"].

You are welcome!

You need to write 'courses' in all uppers. Like this:

   for key, value in COURSES.items():

Do that and your code should work just great! :)

Thanks!
