Output and limitations
Underscore-separated identifiers are common in Python variables and database columns. A lowercase-to-uppercase boundary is split before conversion, allowing typical camelCase names to become snake_case. Acronyms such as HTTPServer may need manual separation when their intended words are ambiguous.
