Part of a Whole 8/9


#1

Hi! Can someone help me with my code. I have visited other topics but was not able to figure it out.

Oops, try again. get_class_average([alice]) resulted in an error: global name 'average' is not defined

# Add your function below!
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    
    return 0.1 * average(student["homework"]) + \
    0.3 * average(student["quizzes"]) + \
    0.6 * average(student["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(lloyd)
    


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

#3

Your program is missing the average() function.


#4

The average function? Where should I put it in my code?


#5

Functions can be written in any order so long as they are not called before they appear in source. Just under the dictionaries will be fine.


#6

I am sorry but can you go into more detail? Isn't my function

def get_class_average(students):

Did I miss something from previous lessons? I have looked on other forums and did not find a average function under the dictionaries.

full code again:

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 get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    
    return 0.1 * average(student["homework"]) + \
    0.3 * average(student["quizzes"]) + \
    0.6 * average(student["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(lloyd)

students = [lloyd , alice, tyler]

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

#7

You don't have an average() function. How do you not see that?


#8

I'm sorry.... I wasn't paying attention. I have fixed my code and found out that part of my code in earlier lessons got deleted.

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

#9

May we assume that your code has the proper indent on the function block, and not the definition line? The function looks correct, otherwise.
