title: extending the python dict class: a comprehensive tutorial
python's dict class is a powerful and versatile data structure, but there are situations where you might want to customize its behavior or add additional functionality. in such cases, extending the dict class can be a useful approach. this tutorial will guide you through the process of extending the dict class in python, providing step-by-step explanations and practical code examples.
before we start extending the dict class, it's essential to have a solid understanding of its basic functionalities. the dict class in python is a mutable, unordered collection of key-value pairs, where each key must be unique.
to extend the dict class, you can create a new class that inherits from dict. this allows you to use all the existing functionalities of a dictionary while adding or modifying behavior as needed.
once you have created a basic extension, you can add custom methods to enhance the functionality of your extended dict class.
to customize the behavior of existing methods, you can override them in your extended class. for example, you might want to modify the _setitem_ method to log whenever a new key-value pair is added.
