What is snake_case?
snake_case is a naming convention where words are separated by underscores and all letters are lowercase. For example, "my variable name" becomes "my_variable_name". The name comes from the way the underscores make the text look like a snake lying flat.
When to Use snake_case
- • Python variables and functions — PEP 8 style guide standard
- • Database column names — user_id, created_at, first_name
- • Ruby on Rails — convention for methods and variables
- • File names — my_script.py, config_file.json
- • Environment variables — DATABASE_URL, API_KEY
snake_case vs kebab-case
Both use lowercase words, but snake_case uses underscores (my_variable) while kebab-case uses hyphens (my-variable). snake_case is preferred in Python and databases, while kebab-case is standard for URLs and CSS class names.
