                      "booleans", "integers", "floats",
                      "arrays", "strings", "exceptions",
                      "conditions", "input", "loops"},
    "Java Basics": {"Java", "strings", "variables",
                    "input", "exceptions", "integers",
                    "booleans", "loops"},
    "PHP Basics": {"PHP", "variables", "conditions",

def covers(prmtr):
    list_courses = []
    for key , val in COURSES.items():
        if prmtr == courses.values():
            list_courses.append(key)
    return list_courses

You are very close. Since prmtr is a also a set, the overlap can be detected using prmtr.intersection(val).
