Please help - I got the list with averages, but it displays error :-(


#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]
}
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)
return float(total)/len(numbers)

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 and score<90:
return "B"
elif score>=70 and score<80:
return "C"
elif score>=60 and score<70:
return "D"
else:
return "F"

students = [lloyd, alice, tyler]

def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return results
print get_class_average(students)

The output is: [80.55, 91.14999999999999, 79.9]

But also error displayed: Oops, try again. get_class_average([alice]) should return a number
May be I didn't undersood the question? Thanks.


#2

from the instructions:

Finally, return the result of calling average() with results

You return results without calling average
