This is my error: Oops, try again. get_class_average([alice]) resulted in an error: list indices must be integers, not str... Can someone tell me what's wrong with my code..

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

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"

students = [lloyd,alice,tyler]

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

return average(results)``````

Try change the 3rd last line to: get_average(student)

#3

It worked! Thank you for helping me!

#4

def get_class_average(students):
students=[lloyd,alice,tyler]
results=[]
for student in students:
results.append(get_average(student))
return average(results)

#5

Figured it out. The "students=[lloyd,alice,tyler]" had to be outside the function...
