@aliyu123,

• select your code
• =click= on the </>-editor-symbol

Present your code with the correct indentation....

A def should be ended with a blank-line..

Hi All,

Below is my code. It comes up with the error

Oops, try again.
get_class_average([alice]) resulted in an error: list indices must be integers, not str

I just cannot get this to work! can anyone help?

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],

"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)
total = total / len(numbers)

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])

``````total = (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"

``````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)``````

I managed to get it to work. The big thing is that you can't use the word "class." I believe it already has a significance in Python.

``````students = [lloyd, alice, tyler]

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