# PLZZZ Help me I have no clue as to what to do 8/9

#1

This is what I have:

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 = float(average(student["homework"])) * 0.1
quizzes = float(average(student["quizzes"])) * 0.3
tests = float(average(student["tests"])) * 0.6
return homework + quizzes + tests
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_average(lloyd)
def get_class_average(students):
results = []
for student in students:
get_average(student);
results.append()
return average(results)

the error is: Oops, try again. get_class_average([alice]) resulted in an error: append() takes exactly one argument (0 given)!!
What do I do?

#2

what result will have to append? here i think it's nothing...there is nothing betwen the () -------> results.append() <------

#3

so what do I do to change it?

#4

Same Problem...
