2. Can a string slice expression be used on a list?

Yes, a string slice expression can be used on a list.

Although the slice notation is commonly used with strings, it can also be used with other sequence types in Python, including lists.

When used with a list, a slice expression returns a new list that contains the specified range of elements from the original list. The syntax for a slice expression with a list is the same as for a string:

my_list[start:end:step]

Here, `start` is the index of the first element to include in the slice, `end` is the index of the first element to exclude from the slice, and `step` is the stride of the slice (i.e., the number of elements to skip between each included element).
