  assert removeItem([1, 2, 3, 4, 2, 5, 2], 2) == [1, 3, 4, 5]
  assert removeItem([10, 10, 20, 30, 10], 10) == [20, 30]
  assert removeItem([5, 5, 5], 5) == []
  assert removeItem([1, 2, 3], 4) == [1, 2, 3]
  assert removeItem([], 7) == []
output: def removeItem(lst, item):
      return [x for x in lst if x != item]
