Hi
Here is my code not sure what i m doing wrong.

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]
}

def average(numbers):
sum(numbers)
total=float(sum(numbers))
a=total/len(numbers)
return a
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
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:
results.append(get_average(student))
return average(results)

Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

It looks like your `students` list is missing...

`students = [ lloyd, alice, tyler ]`

(Try placing it before defining the `get_class_average` function in your code)

#3

Its not working i have tried to adjust your provided list on many places

#4

had the same issue. Cant tell from formatting but make sure your "return average(results)" is out of the for loop

#5

Hi its maybe a `indent` problem so here the code with the correct indent

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

You are legend. Thanks yes its due to indent problem. I have copied yours and its working
