Split up a function

Another engineer on your team has written this function to calculate the mean and median of a sorted list. You want to show them how to split it into two simpler functions: mean() and median()

def mean_and_median(values):
  """Get the mean and median of a sorted list of `values`

  Args:
    values (iterable of float): A list of numbers

  Returns:
    tuple (float, float): The mean and median
  """
  mean = sum(values) / len(values)
  midpoint = int(len(values) / 2)
  if len(values) % 2 == 0:
    median = (values[midpoint - 1] + values[midpoint]) / 2
  else:
    median = values[midpoint]

  return mean, median
