input: Write a function to remove all occurrences of a specified item from a given list. The function should take two parameters, the list and the item to remove. Return the modified list after removing all occurrences of the item.
  assert removeItem([1, 2, 3, 4, 2, 5, 2], 2) == [1, 3, 4, 5]
  assert removeItem([3, 5, 7, 5, 9], 5) == [3, 7, 9]
  assert removeItem([2, 4, 6, 8], 10) == [2, 4, 6, 8]
  assert removeItem([], 1) == []
output: def removeItem(lst, item):
      return [x for x in lst if x != item]
