What is snake_case?

snakecase is a naming convention where words are joined with underscores (). It's popular in programming, especially in Python, for naming variables, functions, and modules. It improves code readability by separating words.

Why use snake_case?

  • Readability: Underscores provide visual separation.
  • Consistency: Snake_case ensures uniform naming, improving maintainability.
  • Python convention: Python's style guide (PEP 8) recommends snake_case for variables and functions.

Alternatives to snake_case

Other naming conventions include:

  • camelCase: Words are concatenated, with each word after the first capitalized (e.g., myVariableName). See our camelCase Converter.
  • PascalCase: Similar to camelCase, but the first word is also capitalized (e.g., MyVariableName). Our PascalCase Converter can help.
  • kebab-case: Words are separated by hyphens (e.g., my-variable-name). Try the kebab-case Converter.
  • SCREAMING_SNAKE_CASE: All letters are uppercase, with words separated by underscores (e.g., `MYCONSTANTVALUE`). Use the SCREAMING_SNAKE Converter to generate this format.
