how do I print the result?
These are the instructions:
Define a function called get_class_average that has one argument class_list . You can expect class_list to be a list containing your three students.
First, make an empty list called results .
For each student item in the class_list , calculate get_average(student) and then call results.append() with that result.
Finally, return the result of calling average() with results .
As you can see from my code, I already completed the first two steps:
loyd = {
“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(tyler))
def get_class_average(class_list):
results =
Thanks so much !! Really appreciate the help !! 
With class_list never having been defined before in the code, how does the system know what class_list is outside this exercise?
Thank you for the help.
If class_list is written as a parameter in a function definition then it is locally declared and would have no role outside of the function, let alone outside of the exercise. Parameters are variables with local scope only.
