6. Just Weight and See need help


#1

I've tried looking in the forums for answers and so far nothing has worked. Can anyone show me what I'm doing wrong?
Here's the code.

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)
print total
total = float(total)
total = total / len(numbers)
return total

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

And this is what it outputs.
File "python", line 32
quizzes = (average(student["quizzes"])
^
SyntaxError: invalid syntax

Yeah any help would be appreciated I've been stuck on this for a while :smiley:

That is a lot of code for something that can be written in simplified form:

def average(scores):
    return float(sum(scores)) / len(scores)

Ditto in the above. It is more complicated than it needs to be.

Count the brackets ( and ). The leading ( is not needed.

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

Ah thank you very much. I'll keep working on my Python skills :slightly_smiling:

Like we all. If any of these examples seem a little ahead of the curve, they probably are. We need to crawl, before we can walk, and walk before we can run. Fortunately it's not a foot race. Spend all the time you need to learn basic mechanics of procedural code, functional code and basic algorithms. Then you can expand on that knowledge. It's a tough game if you miss all the basics and jump right into the more esoteric stuff.
