7/9 what is the problem?


#1

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

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

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))

it keeps returning the error Oops, try again. get_letter_grade(100) returned ('A',) instead of 'A' as expected.

I don't know where these extra parentheses are coming from!

found my own soultion. i removed the commas from my letter grade scores (why was this giving me extra parentheses??)
