input: Write a function to remove all occurrences of a specified item from a given list. The function should return the modified list. Use list comprehension to handle the task efficiently.
  assert removeItem([1, 2, 3, 4, 2, 5, 2], 2) == [1, 3, 4, 5]
  assert removeItem([5, 3, 5, 1, 2, 5], 5) == [3, 1, 2]
  assert removeItem([1, 1, 1, 1], 1) == []
  assert removeItem([], 1) == []
  assert removeItem([1, 2, 3, 4], 5) == [1, 2, 3, 4]
output: def removeItem(lst, item):
      return [x for x in lst if x != item]
