Part of the Whole problem


#1



I have no idea what the problem in my code is. Please help me.


Oops, try again.
get_class_average([alice]) should return a number


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]

# 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"])
    return homework * 0.1 + quizzes * 0.3 + tests * 0.6
    
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:
        get_average(student)
        results.append(get_average(student))
    return results.append(get_average(student))

I don't know why you need to do that but you really just need to append student in students to results and then you need to return average(results) and not results.append(get_average(student)).

The fourth instruction says to explicitly:

  1. Finally, return the result of calling average() with results.

I hope this helps! :slight_smile:

God ■■■■ that was dumb on my part. Just had to change the final return to

return average(results)

Thank you!

You're welcome.

Have fun coding. :slight_smile:
