Just Weight and See

Hi Guys,

I’m getting the following error when running my code:

Oops, try again. get_average(alice) returned 88.85 instead of the expected 91.15

I’m not sure why the average is incorrect, as i havent changed any of the values in the dictionaries.

Was wondering if anyone could see whats wrong.

Thanks

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):
    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 (homework * 0.1) + (tests * 0.3) + (quizzes * 0.6)

Look here:

Reread the instructions (number #4 mainly).


#3
print ("Lloyd: %s" % get_average(lloyd))
print ("Alice: %s" % get_average(alice))
print ("Tyler: %s" % get_average(tyler))

Your results should look something like this…

Lloyd: 80.55
Alice: 91.14999999999999
Tyler: 79.9

Thanks. Such a silly mistake

I had a teacher once who delighted in saying, “There is no grade for effort if you don’t follow the instructions. You get zero on that one.”
