6/9 Alice's messed up grades


#1

Alice is doing some weird stuff with her averages and I can't find the source! Help!

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

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

#2

return 0.1 * homework + other parameters in the return statement.
NOTE: function may only once return result and the multiplier must occur assignment statement
e.g. quizzes = 0.3 * quizzes or
quizzes *= 0.3


#3

Now it makes sense why Alice was getting 97.5, thanks very much!


#4

sorry still didn't get it
def get_average(student):
homework=average(student["homework"])
quizzes=average(student["quizzes"])
tests=average(student["tests"])
return 0.1 * homework
return 0.3 * quizzes
return 0.6 * tests


#5

You can't use the return command multiple times in a single function. So you would write a single return statement followed by the addition of the weighted average, e.g.:
return homework + quizzes + tests


#6

Try this:
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

Hi, The way I fixed it is by doing the following.

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

This seemed yo have worked for me
