Thanks for the kind concern

My question was , why do I get error when i store the output of function get_class_average(students) in average variable and then print average

Error: Float not callable

I have commented these lines as of now (please see last few lines)

Whearas Calling directly the method print get_class_average(students) works fine

My entire code is below

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)

students = [lloyd , alice, tyler]

for student in students:

def get_average(student):

homework = average(student["homework"])

quizzes = average(student["quizzes"])

tests = average(student["tests"])

sum = homework*0.1 + quizzes*0.3 + tests*0.6

return sum

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"
```

score = get_average(lloyd)

grade = get_letter_grade(score)

print grade

students = [lloyd , alice, tyler]

# print students

def get_class_average(students):

results = []

for student in students:

results.append(get_average(student))

return average(results)

for student in students:

#average = float(get_class_average(students))

#print average

#grade = get_letter_grade(average)

#print grade

print get_class_average(students)

print get_letter_grade(get_class_average(students))
