# Part of the Whole, results = [] list contain unwanted values?

#1

My results list show up as [80.55, 91.14999999999999, 79.9, 91.14999999999999, 91.14999999999999], when it should have only 3 values(right?)

This is 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)

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

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

classe = [lloyd, alice, tyler]
def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)

print get_class_average(classe)
print results``````

the function still works, but the results list has those 2 unwanted values, even when not calling the function whatsoever

seems your browser is sending cached data, i get an error with your code:

Traceback (most recent call last):
File "python", line 51, in
NameError: name 'results' is not defined

`results` has a local variable scope, it only exist in the function

Try refreshing the page

#3

that was silly, it is indeed the case

I had results = [] before the loop at some point and it just kept the values from when I was testing

#4

Not accessible outside of the function.

Unless this is an international language exercise, the correct name is, `students`.

Consider when asking a question if you are foisting your own experimental code on an unwitting audience who expect your problem to relate to the actual instructions.
