Something is missing or broken


#1


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

students = [lloyd, alice, tyler]

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))/len(numbers)
    return total

def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests= average(student["tests"])
    grade = homework*.1+quizzes*.3+tests*.6
    Lgrade = get_letter_grade(grade)
    return grade
    
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"

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

average = get_class_average(students)
print average
C_average = get_letter_grade(average)
print C_average

Python is dynamic language?
what does that mean?

suppose...

x = 2

x is an integer type there but when you do this..

x ="string here"

now x is of string type,

in same way when you wrote this..

average = get_class_average(students)

You overwrote your function with a number type,
Functions are objects, They belong to function class.
You need to use any other identifier name so it does not override function!

Note:
make sure you define your students dictionary after you define your dictionaries.
students = [lloyd, alice, tyler]
