input: Write a function to move all zeroes in a list to the end of the list. If the list is empty, the function should return an empty list.
  assert move_zeroes([3, 0, 1, 0, 5, 0, 2])==[3, 1, 5, 2, 0, 0, 0]
  assert move_zeroes([0, 0, 0, 0])==[0, 0, 0, 0]
  assert move_zeroes([1, 2, 3, 4])==[1, 2, 3, 4]
  assert move_zeroes([])==[]
output: def move_zeroes(lst):
      if not lst:
          return lst
      zeroes = lst.count(0)
      lst = [x for x in lst if x != 0]
      lst.extend([0] * zeroes)
      return lst
