Lesson 9


#1


I am getting error
Oops, try again. Did you remember to print the average of the class? It looks like "None" wasn't printed.

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"]) * 0.1
    quizzes=average(student["quizzes"]) * 0.3
    tests=average(student["tests"]) * 0.6
    return homework + quizzes + 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))
        
def get_class_average(students):
    results=[]
    for student in students:
        results.append(get_average(student))
    print average(results)
   
        
#students=[lloyd, alice, tyler]

Why are you printing this? A function ends when the return keyword is reached.... Do you get the hint? :slight_smile: There's no need to print at the moment.... You forgot something.... I mentioned it earlier :slight_smile:
