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

def covers_all(single_set):
    all_course = []
    single_set = set(single_set)
    for x,y in COURSES.items():
        if items[0] in y and items[1] in y:
            all_course.append(x)
    return all_course       







def covers(set_topics):
    course = []
    for x,y in COURSES.items():
        if set_topics.intersection(y):
            course.append(x)
    return course
