Part of the Whole


#1

I can't figure out where is the problem.
So,can I teach me how to fix it ?

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]
}

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"])
    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"
        
students = (lloyd,alice,tyler)

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

After I exucute this program,following message appear
"Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected"


#2

get_class_average should return average value of students' average grades, however in your code function doesn't return average value of results

This part needs improvement


#3

I fixed mentioned part,the problem is solved.

def get_class_average(students):
results = []
for student in students:
return results.append(get_average(student))
Thank you so much :slightly_smiling:


#4

i have the same problem


#5

Im having the same issue. Someone please help


#6

I looked at your 3 versions of codes over and over again and did not find what is the difference. So this means: it does not give any solution to my code, I have got the same error and cannot fix it
