How is everyone doing


#1



it keeps saying something
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


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 = average(student["homework"])
    quizzes =  average(student["quizzes"])
    tests = average(student["tests"])
    
    weighted_homework = homework * 0.10
    weighted_quizzes = quizzes * 0.30
    weighted_tests = tests * 0.60
    
    return weighted_homework + weighted_quizzes + weighted_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"
        

print(get_letter_grade(get_average(lloyd)))

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

print(results)
print(get_letter_grade(results))
