How Is Everybody Doing?


#1

When I tried to run the code it throws an error:

Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

Which part/code I was wrong?

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

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

the students list you build in 3. put it together is missing

also, function calls execute the function so they should be outside the function (hint: indent)


#3

Never mind, I got it. My print part was inside the function. Now its working :slight_smile:
