plez help me on this lesson

``````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)
return float(total)/len(numbers)
def get_average(student):
homework=average(student["homework"])
quizzes=average(student["quizzes"])
tests=average(student["tests"])
return homework*0.1+quizzes*0.3+tests*0.6
if score>=90:
return "A"
elif score>=80:
return "B"
elif score>=70:
return "C"
elif score>=60:
return "D"
else:
return "F"

def get_class_average(students):
results=[]
for student in students:
results.append(get_average(student))
return average(results)
students = [lloyd, tyler, alice]
print get_class_average(students)

You need to have a list of the students:

``students = [lloyd, alice, tyler]``

and you need to print the class average of the students and the letter grade of the class average of the students:

``````print(get_class_average(students))

#3

didn't I do that? * groan *

#4

Actually in your given code, your only print statement outside of a function was in a comment, and you did not have a list containing the student dictionaries.

#5

it is line 41? right?

#6

Your last 3 lines shouldn't be indented.
