Sending a Letter sends the wrong grade

It's saying that get_letter_grade(89) returned 'A' instead of 'B' as expected. I have done everything they said and I don't know why this is happening.


Replace this line with your 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)
    return total# Add your function below!

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

def get_letter_grade(score):
    score = float or int
    if score >= 90:
        return "A"
    elif score >= 80 and score < 90:
        return "B"
    elif score >= 70 and score < 80:
        return "C"
    elif score >= 60 and score < 70:
        return "D"
    else:
        return "F"

print get_letter_grade(get_average(lloyd))

''score= float or int''?


#3

in the get_letter_grade function you do not need to put two conditions in the elif statements. the code should go like this:

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"

Thank you that worked
