Keyword Arguments

Keyword arguments are a feature in programming languages that allow functions to be called with arguments specified by parameter names rather than just their positions. This makes function calls more readable and flexible, as arguments can be passed in any order and default values can be easily set. They are commonly used in languages like Python, Ruby, and JavaScript to enhance code clarity and maintainability.

Also known as: named arguments, keyword parameters, kwargs, named parameters, keyword args

Why learn Keyword Arguments?

Developers should learn keyword arguments to write more expressive and self-documenting code, especially when functions have many parameters or optional settings. They are essential for APIs, configuration functions, and libraries where readability and flexibility are priorities, such as in data science libraries like pandas or web frameworks like Django. Using keyword arguments reduces errors from argument order and improves code maintainability in collaborative projects.
