I get this error. I cannot see where I went wrong and why it will not print. Any assistance will be greatly appreciated.

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


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):
    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"
    
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(students)
print get_letter_grade(get_class_average(students))

Hi @cod3_chaser, I just tested your code and it works fine. Have you tried refreshing the page? :thinking:


#3

I have the same error.


#4

I tried refreshing my browser and it still doesn't work. In the console, I have this

Traceback (most recent call last):
File "python", line 51, in
NameError: name 'students' is not defined


#5

You didn't put your dictionaries in the a list (called students) that will contain the dictionaries. That's why it says students is not defined because it doesn't exist. Reread the instructions in Put It Together if you need a hint on what to do.


#6

you were supposed to make a variable called students on line 19
students = [lloyd, alice, tyler]


#7

I got it Thanks!!!!!!


#8

Thank you so much for your help.


#9

It is weird since I passed the put it together exercise. I see it there but for some reason, it was not there in this exercise. Again thank you for your help.


#10
