Punctuation is removed and spaces are replaced by single [[underscore]]s. Normally the letters share the same case (e.g. "UPPER_CASE_EMBEDDED_UNDERSCORE" or "lower_case_embedded_underscore") but the case can be mixed, as in [[OCaml]] variant constructors (e.g. "Upper_then_lowercase").<ref>{{Cite web|url=http://caml.inria.fr/resources/doc/guides/guidelines.en.html|title=Caml programming guidelines|website=caml.inria.fr|language=en|access-date=2017-03-31}}</ref> The style may also be called ''pothole case'', especially in [[Python (programming language)|Python]] programming, in which this convention is often used for naming variables. Illustratively, it may be rendered ''snake_case'', ''pothole_case'', etc.. When all-upper-case, it may be referred to as ''screaming snake case'' (or ''SCREAMING_SNAKE_CASE'') or ''hazard case''.<ref name="Ruby" />
