## snake_case `snake_case` is a naming convention where each word in a compound term is separated by an underscore (`_`) and all letters are lowercase. It is widely used in Python programming, especially for naming variables, functions, and file names. ### Key Points: - **Readability:** The underscores make it easy to read and understand the purpose of identifiers. - **Convention:** Adhered to in the Python community for a consistent coding style. ### Examples in Python: - `user_name` - A variable to store the name of a user. - `calculate_age` - A function that calculates and returns an age. - `employee_record` - A dictionary holding data about an employee. This naming style enhances code readability and consistency, particularly in collaborative environments.
