I need help (update)


#1


lloyd = {
    "name": "Lloyd",
    "homework": [90.0, 97.0, 75.0, 92.0],
    "quizzes": [88.0, 40.0, 94.0],
    "tests": [75.0, 90.0]
}

    "name": "Alice",
    "homework": [100.0, 92.0, 98.0, 100.0],
    "quizzes": [82.0, 83.0, 91.0],
    "tests": [89.0, 97.0]
}
tyler = {
    "name": "Tyler",
    "homework": [0.0, 87.0, 75.0, 22.0],
    "quizzes": [0.0, 75.0, 78.0],
    "tests": [100.0, 100.0]
}

def average(numbers):
    total = sum(numbers)
    total = float(total)
    return total/len(numbers)
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return .10 * homework + .30 * quizzes + .60 * tests
    
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 get_average(lloyd)

print get_letter_grade(get_average(lloyd))
def get_class_average(students):
    results = []
    students = [lloyd, alice, tyler]
    for student in students:
        result.append(get_average(student))
    return average(results)

I don't know what to do

Well... What's the error? And the link to the lesson?

Please correctly format your code. :slight_smile:

lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

Add your function below!

def average(numbers):
total = sum(numbers)
total = float(total)
result = total/len(numbers)
return result
def get_average(student):
homework = average(student["homework"])
quizz = average(student["quizzes"])
test = average(student["tests"])
return .1*homework + .3*quizz + .6*test
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"

def get_class_average(students):
results=[]
for item in students:
result = get_average(item)
results.append(result)
return average(results)
