Student becomes the teacher - Part of the Whole

no error message - however everyone seems to be using a different argument in the code to get the same result… dont know why…

Please look at the last part of the code: for the function def class_average - in the exercise it clearly states the argument of that function should be “class_list” - however, everyone seems to be using “students”… can anyone explain to me why?


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)

print ("Lloyd: %s" % get_average(lloyd))
print ("Alice: %s" % get_average(alice))
print ("Tyler: %s" % get_average(tyler))

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 ("Lloyd: %s" % get_letter_grade(get_average(lloyd)))

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

the course recently got upgraded to new enviroment, one of the very few small changes made was changing the name of function parameter from students to class_list, so if you find topics from before the the first of this month, its the old enviroment where students parameter was still used
