# Add your function below!
def get_average(student):
    homework = average(student["homework"])
    tests = average(student["tests"])
    quizzes = average(student["quizzes"])
    result = homework*0.1 + tests*0.6 + quizzes*0.3
    return result
def average(numbers):
    total = sum(numbers)
    media = float(total)/len(numbers)
    return media

def get_letter_grade(score):
    if score >=90:
        return "A"
    elif score >=80:
        return "B"
    elif score >= 70:
        return "C"
    elif score >= 60:
        return "D"
    else:
        return "F"
print "%s" % get_letter_grade(get_average(lloyd))
def get_class_average(students):
    results=[]
    for i in students:
        results.append(get_average(i))
    return average(results)
students = ['lloyd', 'alice', 'tyler']

print "%s" % get_class_average(students)

for j in students:
    print "%s" % get_letter_grade(students)

#2

Then, print the result of get_letter_grade for the class's average.

this means you need to call get_class_average inside of calling get_letter_grade, i don't see why you need a loop for this
