        If array-like, it will be broadcast and applied elementwise.

            Specifying the set of characters to be removed.
            All combinations of this set of characters will be stripped.
            If None then whitespaces are removed. If array-like, it is broadcast.
        side : {"left", "right", "both"}, default: "both"
            Side from which to strip.
