"In Python, a callable is any object that you can call using a pair of parentheses and, optionally, a series of arguments. Functions, classes, and methods are all common examples of callables in Python. Besides these, you can also create custom classes that produce callable instances. To do this, you can add the special method to your class. Instances of a class with a .__call__() method behave like functions, providing a flexible and handy way to add functionality to your objects."
"Understanding how to create and use callable instances is a valuable skill for any Python developer. In this video course, you'll: Understand the concept of callable objects in Python Create callable instances by adding a method to your classes Compare and and understand their distinct roles Build practical examples that use callable instances to solve real-world problems What's Included: Downloadable Resources:"
A callable is any object that can be invoked with parentheses and optional arguments. Functions, classes, and methods are common callables. Custom classes can produce callable instances by defining the special __call__ method. Instances that implement __call__ behave like functions and can encapsulate both behavior and state, offering flexible, reusable interfaces. The course explains how to create callable instances, compares callables' distinct roles, and presents practical examples that apply callable instances to real-world problems. Mastering callable instances helps write cleaner APIs, implement function-like objects, and apply patterns like decorators, factories, and stateful callables. Downloadable resources support hands-on practice.
