input: Write a function to remove all occurrences of an item from a given list. The function should take two parameters: the list and the item to be removed. Return the modified list without the specified item.
  assert removeItem([1, 2, 3, 4, 2, 5, 2], 2) == [1, 3, 4, 5]
  assert removeItem([1, 2, 3, 1, 4, 1], 1) == [2, 3, 4]
  assert removeItem(['a', 'b', 'a', 'c'], 'a') == ['b', 'c']
  assert removeItem([], 1) == []
output: def removeItem(lst, item):
      return [x for x in lst if x != item]
