How is everyone doing?


#1

I need help as i am stuck on this code. I done what it sayed and it failed.

The error code says:
Oops, try again. Did you remember to print the average of the class? It looks like "83.8666666667" wasn't printed.

Here is my code:
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)
total = total /len(numbers)
return total
students = [tyler, alice, lloyd]
def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])

return 0.1 *homework + 0.3 *quizzes + 0.6*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"
def get_class_average(students):
results =[]
for students in students:
results.append(get_average(students))
return average(results)
print get_class_average
print get_letter_grade


#2

you have to call that function in the last two line like this:
print get_class_average([lloyd,alice,tyler])
print get_letter_grade(average)


#3

thx il try see if it works


#4

it comes up with this:
Did you remember to print the letter grade for the class's average?


#5

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]}

students = [lloyd,alice,tyler] #does I need this?

def average(numbers):
    total = float(sum(numbers))
    result = total/len(numbers)
    return result

def get_average(student):
    homework = average((student)["homework"])
    quizzes = average((student)["quizzes"])
    tests = average((student)["tests"])
    result = ((homework * 0.1) + (quizzes * 0.3) + (tests * 0.6))
    return result

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 student in students:
        get_average(student)
        results.append(get_average(student))
    return average(results)
    
print get_class_average(students)
print get_letter_grade(get_class_average)

I think I have the same problem with the lines as 14nsharpe

print get_class_average(students)
print get_letter_grade(get_class_average)

It prints 83.8666666667 and A but put out the error:
'Oops, try again. Did you remember to print the letter grade for the class's average?'

Any hint? Many thanks!

I had the same problem. For the last line, put this:

print get_letter_grade(get_class_average(students))

Should work :slight_smile:


#7

Last 2 lines should be something like this:

print get_class_average([lloyd,alice,tyler])
print get_letter_grade(get_class_average([lloyd,alice,tyler]))


#8

You could go with :

print get_class_average(students)
print get_letter_grade(get_class_average(students))
