Part of the Whole

Hi I receive an error executing this 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]
}

students = [lloyd, alice, tyler]

def average(numbers):
total = sum(numbers)
total = float(total)
avgr = total / len(numbers)
return avgr

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

def get_letter_grade(score):
if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"
print get_letter_grade(get_average(lloyd))

def get_class_average (students):
results = []
for student in students:
get_average(student)
results.append(get_average(student))
return average(results)``````

ERROR MESSAGE: Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected.

Any ideas?

a function ends the moment a return keyword is reached, if the return keyword is reached in a loop, the loop simply breaks

in other words, your loop breaks in the first iteration

Wow, thank you so much!
One TAB breaks the whole code

Thanks again!
