+///
+/// ## Why is this bad?
+/// Calling `str.split()` without `maxsplit` set splits on every delimiter in the
+/// string. When accessing only the first or last element of the result, it
+/// would be more efficient to only split once.
+///
+/// ## Example
+/// ```python
+/// url = "www.example.com"
+/// prefix = url.split(".")[0]
+/// ```
+///
+/// Use instead:
