Hi,

I've been checking all answers in forums here and even copied other user's code to make mine work, but it keeps showing this error message: "File "python", line 51 return average(results) SyntaxError: invalid syntax". I tried changing the identation of the "return" line, I checked character by character for misspells... nothing seems to work. Any idea?


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],

# 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"])
    quizzes=average(student["quizzes"])
    tests=average(student["tests"])
    return 0.1*homework + 0.3*quizzes + 0.6*tests

    elif 79 < score < 90:
        return "B"
    elif 69 < score < 80:
        return "C"
    elif 59 < score < 70:
        return "D"
    else:
        return "F"

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

Hi this part

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

the return statement should be inside the function get_class_average not inside the for loop.

.........
    for student in students:
        results.append(get_average(student)
    return average(results)

then here its missing on ) for clossing .append()

 results.append(get_average(student)

Ok, I just realized there was the ) symbol left at the very moment I submitted the topic. Thank you! :slight_smile:
