Part of the Whole


#1



Hey guys, this is the exercise I am stuck on - https://www.codecademy.com/courses/python-beginner-en-qzsCL/1/4?curriculum_id=4f89dab3d788890003000096


The error I am getting is :

File "python", line 50
for student in homework
^
SyntaxError: invalid syntax


Instead it should be returning the averages of the averages of the students(please look at the exercise)


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))
    result = float(total)/len(numbers)
    return result
    
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"
    if score >= 80:
        return "B"
    if score >= 70:
        return "C"
    if score >= 60:
        return "D"
    else:
        return "F"
        
def get_class_average(students):
    
    students = ["Tyler", "Alice", "Lloyd"];
        
    
    results = []
    for student in homework
        results.append(get_average(student))
    return average(results)

For starters, this list definition should be moved into the outer scope. Just below the dictionaries is a good place to move it.

The object is students, a list of which this is one element reference.

    for student in students:

aha, thank you so much that makes alot more sense now, I originally put students but I forgot the colon so i changed it. Nevertheless thank you so much
