8.Part of the whole


#1

This is literally killing me. I have looked through all the other solutions and still cant get this to work. Can anyone see something i have missed

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):
    sum(numbers)
    total = float(sum(numbers))
    return total / len(numbers)


def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return sum([homework *0.1, quizzes *0.3, tests *0.6])
    
def get_letter_grade(score):
    score=float(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))
        return average(results)

#2

This line should not be necessary. score is a float already (or should be).

From the looks of it, the students list is missing.

students = [ lloyd, alice, tyler ]

#3

Nope, that doesn't work.

The code in post #1 will return the average returns the wrong output.


#4

This line is not needed, and is not a statement. It may be removed.


#6
 def get_class_average(students):
     results = []
     for student in students:
          results.append(get_average(student))
     return average(results)`
