9/9 Completely Stuck and I'm not good at coding


#1

I can't figure this out at all. I'm pretty bad at coding because I don't understand a lot of the terminology used in Python. Anyway, here's what I've got:

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]
}

Add your function below!

def average(numbers):
total = sum(numbers)
total = float(total)
total = total/len(numbers)
return total

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_class_average(student)
print get_letter_grade(get_class_average(student))

Sorry that it's not indented, I can't figure out how to do that. Also, the error message is: Traceback (most recent call last):
File "python", line 45, in
NameError: name 'student' is not defined


#2

you should call the function with variable 'lloyd' (as following instruction) rather using 'student'

print get_letter_grade(get_average(lloyd))

#3

sorry, forget what i say above, i mix up the lessons

the students list should be created first in order to call it in function

students = [lloyd, alice, tyler]

add the code before print it out
