8/9 Getting an error though code is correct and prints correctly

Code should be spitting out the averages for each student in the class. It does this, however I keep getting an error message saying “get_class_average([alice]) should return a number.” I’m pretty sure my code is returning numbers…not sure why it’s just Alice that isn’t. Any thoughts?



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]
}

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

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

def get_average(student):
  homework =average(student['homework'])
  quizzes =average(student['quizzes'])
  tests =average(student['tests'])
  
  weight = homework*0.1 + quizzes*0.3 + tests*.6
  return weight
    
def get_class_average(class_list):
  results = []
  for student in class_list:
    results.append(get_average(student))
  return results

classy = [lloyd, alice, tyler]
print get_class_average(classy)

You are returning a list. The list contains all the weighted averages, but the return should be the average of those.

return sum(results) / len(results)
