My code output is correct but I'm not able to complete the task

The covers_all(): function should compare a given set with a dict and return a list with the keys if the dict[key] contains all the set values.

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"} }

Function input >>>> covers_all( {'variables','inputs')

Function output >>>> ['Python Basics', 'Java Basics']

    "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_1):
    lista = []
    for item in set_1:
        for key in COURSES.keys():
            if item in COURSES[key]:
    lista = set(lista)
    lista = list(lista)
    return lista

def covers_all(set_2):
    lista = []
    aux = {}
    for key in COURSES.keys():
        aux = set_2 & COURSES[key]
        if len(aux) == len(set_2):
    return lista
