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]
}

# Add your function below!

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


#2

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


#3

It worked! Thank you for helping me!


#4

Please help. What am I doing wrong here:
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...
