input: Write a function to remove duplicates from a given list and sort it in ascending order. The function should return the sorted list.
  
  def remove_duplicates_and_sort(my_list):
      my_list = list(dict.fromkeys(my_list))
      my_list.sort()
      return my_list
  
  assert remove_duplicates_and_sort([2, 8, 5, 2, 6, 3, 4]) == [2, 3, 4, 5, 6, 8]
  assert remove_duplicates_and_sort([1, 1, 1, 1]) == [1]
  assert remove_duplicates_and_sort([]) == []
  assert remove_duplicates_and_sort([9, 8, 7, 6, 5, 4, 3, 2, 1]) == [1, 2, 3, 4, 5, 6, 7, 8, 9]
