## 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.
