Oops, try again. alice does not seem to contain the correct dictionary, it should contain: {'quizzes': [82.0, 83.0, 91.0], 'tests': [89.0, 97.0], 'name': 'Alice', 'homework': [100.0, 92.0, 98.0, 100.0]}


I don't know what is wrong with my code. Plz help me.


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

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


#2

that's strange, try refreshing the page


#3

Did the console show any error messages??


#4

Oops, try again. alice does not seem to contain the correct dictionary, it should contain: {'quizzes': [82.0, 83.0, 91.0], 'tests': [89.0, 97.0], 'name': 'Alice', 'homework': [100.0, 92.0, 98.0, 100.0]}

is the error message


#5

No, I didn't mean that. I asked if there were any syntax errors or something.


#6

I have completed this exercise. As the code is really big it might be difficult to find out what happened. I can give my code if you want.


#7

could you give me that code? plz


#8

This is 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]
}

# Add your function below!
def average(numbers):
    total = float(sum(numbers))
    average = total / len(numbers)
    return average

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

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"

grade = get_letter_grade(get_average(lloyd))
print grade

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

print get_class_average([alice, tyler])

#9

Doesn't work for me and i did it exactly like yours


#10

Never mind, I wrote result.append(get_average(student)) instead of results.append(get_average(student))
