Prototype design pattern in python

the prototype design pattern is a creational design pattern that is used when creating new objects by copying an existing object, known as the prototype. this pattern is useful when creating new objects is more expensive or complicated compared to copying an existing object.

here is a step-by-step tutorial on how to implement the prototype design pattern in python:

1. define the prototype class:

2. create concrete prototype classes:

3. create an instance of the prototype class and register concrete prototype objects:

4. clone prototype objects to create new objects:

in this example, we defined a prototype class that maintains a dictionary of registered prototype objects. we can register concrete prototype objects (rectangle and circle) and then clone them to create new objects with specific attributes.

the prototype design pattern helps in reducing the complexity of object creation and allows for creating new objects based on existing objects.

i hope this tutorial helps you understand and implement the prototype design pattern in python! let me know if you have any questions.
