Part of the whole.What is wrong with my code?


#1

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)
x = total /len(numbers)
return x
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'

def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
average(results)
return results

print get_class_average([alice])

I get output:
[91.149999]
and error is:
Oops, try again. get_class_average([alice]) should return a number

@l1palas: That's because you're returning a list , not just a value.
The output was [91.149999] and such thing represents a list.

Instead of returning the list, return the average of it by putting return before your average(results).

Also, check the instructions! I believe you were supposed to have a list of students containing lloyd, alice and tyler but not only alice.

Thank you!..........
