Stuck in the 'Just Weight and See' exercise


#1

link: exercise

error message:

get_average(alice) returned 93.4 instead of the expected 91.15

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 = float(sum(numbers))/len(numbers)
  return total

def get_average(student):
  homework = average(student['homework']) * 0.6
  quizzes = average(student['quizzes']) * 0.3
  tests = average(student['tests']) * 0.1
  sum = homework + quizzes + tests
  return sum

what am I doing wrong? what is the problem and what should I change?

thanks ;-;


#2

Check the indentation of your methods, specifically the returns


#3

Check the instructions. More specifically, look at the weighted factor values for each of the scores:

Homework is 10%, quizzes are 30% and tests are 60%.
