Hello!

This is my problem : > Oops, try again. get_average(alice) raised the following error: 'list' object has no attribute 'average'.

The massage appears after this 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]
}

# Add your function below!
def average(numbers):
    total = sum(numbers)
    total = float(total)
    return total / len(numbers)
def get_average(student):
    homework = student["homework"].average()
    quizzes = student["quizzes"].average()
    tests = student["tests"].average()
    
    return 0.1 * float(homework) + 0.3 * float(quizzes) + 0.6 * float(tests)

I don't really understand what I'm doing wrong. Could anyone help me, please?

Hi, @toivoscr ,

In these exercises, average has been defined as a function, but not a method. Therefore, this is not a correct call ...

homework = student["homework"].average()

Instead, you need to pass student["homework"] as an argument to the average function.

The two statements that follow that one also need to be revised.

Thank you, @appylpye ! Now it works.
