``````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=float(total)/len(numbers)
def get_average(student,):
homework=average(student["homework"])
quizzes=avarage(student["quizzes"])
tests=avarege(student["tests"])
weights=homework*0.1+quizzes*0.3+tests*0.6
return weights``````

I read other topic but I couldnt do this exercise.Where is my mistake ?

Here,

and here,

for a start. The commas may be tripping up the SCT. Python doesn't seem to object so must be ignoring them (no effect).

``````>>> def foo(bar,):
return bar

>>> foo("foobar")
'foobar'
>>>``````

Try removing the commas and see if it passes.

check how to spell average + @mtf = answer

#4

These are the lines our young colleague is referring to.

``````    total=float(total)
total=float(total)/len(numbers)``````

The second line above does not need to be declared a float, again. It is a float.

``total = total / len(numbers)``
