I am getting this error message : Oops, try again. get_class_average([alice]) resulted in an error: 'str' object is not callable. But i believe my code is correct.

my complete 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]
}
students = [lloyd,alice,tyler]
# Add your function below!
def average(numbers):
     
    total = sum(numbers)
    total = float(total)
    average = total/len(numbers)
    return average
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    get_average = 0.1 * homework + 0.3 * quizzes + 0.6 *tests
    return get_average
    
def get_letter_grade(score):
    if score >= 90:
        return "A"
    elif score >= 80:
        return "B"
    elif score >= 70:
        return "C"
    elif score >= 60:
        return "D"
    else:
        return "F"
get_average = get_letter_grade(lloyd)  
print get_average

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

the problem is actually here:

get_average = get_letter_grade(lloyd)  
print get_average

by storing the result of calling get_letter_grade into get_average, you overwrote your get_average function, which means now get_average contains a string, so when you try to call get_average here:

results.append(get_average(student))

you get an error saying a string is not callable. Which is true.

don't overwrite your function
