Screen shot of error unable to debug


#1

"Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade"

this is the error what does it mean???
the 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]
}

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"])*0.10
quizzes=average(student["quizzes"])*0.30
tests=average(student["tests"])*0.60
return homework+quizzes+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'
def get_class_average(students):
results=[]
for item in students:
x=get_average(item)
results.append(x)
x=average(results)
return x

print get_class_average([lloyd,alice,tyler])
print get_letter_grade(get_class_average([lloyd,alice,tyler]))


#2

you need to paste and format your code here so we can see exactly what you did


#3

i have added only the last 2 sentences rest were provided to me beforehand


#4

solution???did you identify the error in my code?


#5

There's nothing wrong with it. it might be that you didn't do the indentations properly but i just tested it and its fine

    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)
	return total/len(numbers)
def get_average(student):
	homework=average(student["homework"])*0.10
	quizzes=average(student["quizzes"])*0.30
	tests=average(student["tests"])*0.60
	return homework+quizzes+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'
def get_class_average(students):
	results=[]
	for item in students:
		x=get_average(item)
		results.append(x)
		x=average(results)
	return x

print get_class_average([lloyd,alice,tyler])
print get_letter_grade(get_class_average([lloyd,alice,tyler]))

i did the indentation and the output is also showing up still that error is there
