I may be being stupid but can someone look at this code and figure out how the .1 , .3, and .6 came to be the right input for the code.

The bullet point was “Multiply the 3 averages by their weights and return the sum of those three. Homework is 10%, quizzes are 30% and tests are 60%.”

See code below:

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]

}

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”])

total = homework *.1 + quizzes * .3 + tests * .6

return total

Thanks in advance, sorry if it a stupid question but I’m just learning this and I can’t figure this out.
