Hi guys,
I got this message, Could anyone help plz: Oops, try again. get_class_average([alice]) resulted in an error: 'float' object is not callable

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

Sure here is:

``````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):
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 (homework *0.1 + quizzes*0.3 + tests * 0.6)

if score >=90:
return "A"
elif (score >=80):
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"
average = get_average(lloyd)

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

that took me longer to find then i like to admit, here:

``average = get_average(lloyd)``

this will overwrite your average function, so now when calling average here:

``average(student["homework"])``

you have a problem. remove this lines:

``````average = get_average(lloyd)
