8/9 get_class_average([alice]) resulted in an error: 'float' object is not callable


#1

Hey guys,

I keep getting the error message get_class_average([alice]) resulted in an error: 'float' object is not callable.

This is 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]
}

student = [lloyd, alice, tyler]
# Add your funct

def average(numbers):
    total = sum(numbers)
    total = float(total)/len(numbers)
    return total
 
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)
    
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"
        
average = get_average(alice)
letter = get_letter_grade(average)
print letter

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

What am I doing wrong?

I found the answer in the forums!

The Codecademy Submission Correctness tests gives an error if you create a variable with the same name as a pre-existing function.

As I had defined a function called average, deleting this code

average = get_average(alice)
letter = get_letter_grade(average)
print letter

solved my issue.

Cheers
