Code compiles but Code Academy throws error


#1



Exercise: Student becomes teacher

Error: Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

Help! Code runs but throws the above Code Academy error. I have gone through the posts where users have encountered similar error and checked for the possible solutions. What am i overlooking in the below 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]

def average(numbers):
    
    total=sum(numbers) 
    total = float(total)
    total = 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"


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

average=get_class_average(students)
print average
print get_letter_grade(average)

You may be overwriting a function you've come to depend upon. Be careful not to use variables with the same name as your functions. Use something else, like, avg or some such.

Bullseye!
Thanks! That worked. Had been stuck on this since yesterday.
