This is my code:

``````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)
total = 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

score = 0
if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

Had to delete score = 0.

Thought that "01. Define a new function called get_letter_grade that has one argument called score. Expect score to be a number." meant that I had to define a numeric value to 'score'.

Very good...
The function-talk would then be

As the get_letter_grade function takes 1 parameter score
which is used as a variable within the FUNCTION-BODY

Now as you want to call / execute the get_letter_grade function
and the get_letter_grade function was defined as having 1 parameter
you will have to provide 1 argument which should be a number Value
in our case that would be the return-Value of get_average(lloyd)
like
but
as the get_letter_grade function will return a string Value with NODisplay
we are using the print statement
like
