In Python, both lists and strings use the same square bracket indexing and slicing, like `my_list[1:4]` or `my_string[1:4]`. The real difference is what you harvest: slicing a list gives you a new list, slicing a string gives you a new string. You can change a list's element, `my_list[0] = 'onion'`, but you cannot change a single character in a string—it's immutable, like my father's old well that ran dry. This reminds me of trying to swap a single rotten potato in a stored sack; with a string, you must make a whole new sack, but with a list, you just reach in and replace it.
