Its shows this error (getclass_average([alice]) resulted in an error: unsupported operand type(s) for +: 'int' and 'function')_

What should i do?

``````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(n):
total = sum(n)
total = float(total)
total = total/len(n)

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"

print get_average(lloyd)

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

either place this:

``get_average(item)``

inside of append, or store the result of calculating the get_average in a variable and append the variable to the list

Thanks!!! It worked!!
But just for learning purposes, it wasn't working because "item" wasn't storing anywhere?

#4

the result of calling get_average with argument item wasn't stored anywhere, yes
