# There’s an error somewhere

#1

i’ve been having issues with this as well. but i’ve gotten most of the code but there’s an error somewhere. here’s my 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]
}

def average(numbers):
total=sum(numbers)
total=float(total)
total=total / len(numbers)
def get_average(student):
homework=average(student[“homework”])
homework=average(student[“quizzes”])
homework=average(student[“tests”])
return (0.1 * average(student[homework]) + 0.3 * average(student[quizzes]) + 0.6 * average(student[tests]))

the error is as followed

get_average(alice) raised the following error: 93.0

any tips? suggestions?

The first three lines are not needed if you are going to call the average function in the return statement. Also, remove the parens from the beginning and end.

if i do that (heres 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]
}

def average(numbers):
total=sum(numbers)
total=float(total)
total=total / len(numbers)
def get_average(student):
return 0.1 * average(student[homework]) + 0.3 * average(student[quizzes]) + 0.6 * average(student[tests])

i get this

get_average(alice) raised the following error: global name ‘homework’ is not defined

also the parentheses were for the line breakers. or these symbols \

Recall that key names are strings. Be sure to use quotes.
