This distinction becomes important when we discuss the mutable default pitfall later in this section. For now, understand that each call either uses your provided value or falls back to the pre-defined default. Multiple Default Parameters Functions can have multiple default parameters. This is common in data processing functions where you want sensible defaults: Notice how the function remains useful with minimal arguments. The caller only needs to specify the table name, and sensible defaults handle pagination and sorting. This pattern appears constantly in database utilities, API clients, and data processing libraries. Here are examples of the most common default parameters
