8. where's the calculation error?


#1

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]
}


# Add your function below!
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'])
    '''homeworkX = homework * 10/100 #average(numbers)
    quizzesX = quizzes * 30/100#average(student)
    testsX = tests * 60/100#average(student)
    total = homeworkX + quizzesX + testsX'''
    return 0.1*homework+0.3*quizzes+0.6*tests
    
    #a = [lloyd,alice,tyler]
    #print get_average(lloyd)
    
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'
        
students = [lloyd, alice, tyler]

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

The error:

Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

for student in studentss:
