Default and Keyword Arguments in Python

Function calls do not have to repeat the same values or leave readers guessing what each argument means. This Block shows you how to give parameters useful default values, override them when needed, and pass arguments by name to make calls easier to understand.

What you will learn:

  • Define optional parameters with safe string, number, and boolean defaults
  • Call functions with or without overriding their default values
  • Place required parameters before parameters with defaults
  • Pass keyword arguments by parameter name and change their order safely
  • Mix positional and keyword arguments without assigning one parameter twice
  • Skip an earlier default while overriding a later one

By the end, you will be able to design flexible beginner-friendly functions and write calls that explain themselves.
