Snake Case

Snake case is widely used in programming for variable names, function names, configuration files, and database fields. It's especially common in Python, where it's the preferred naming style for most identifiers. The format improves readability by clearly separating words with underscores while keeping all characters in lowercase.

Unlike camel case, which uses capital letters to mark word boundaries, or kebab case, which uses hyphens, snake case avoids mixed casing or special characters. It’s also used for constants in uppercase form, like MAX_LENGTH, in many languages.

Developers appreciate snake case for its simplicity, consistency, and clarity—especially when scanning large codebases. It helps reduce ambiguity and supports naming conventions across scripting, backend, and database contexts. Snake case remains one of the most accessible styles for both beginners and experienced developers.
