Prototype Pattern 🛠️

Overview 📖

The Prototype Pattern is used to create duplicate objects while keeping performance in mind. It helps in creating objects more conveniently.

Use Cases 🔍

• When the classes to instantiate are specified at runtime.
• For avoiding the overhead of creating objects in a standard way (e.g., using new), especially when it is complex or time-consuming.

Implementation 🛠️

The prototype.py file contains a Prototype base class and a ConcretePrototype class that clones itself.

Example Usage 📝

prototype_original = ConcretePrototype1(1001)
prototype_clone = prototype_original.clone()
print("Original:", prototype_original)
print("Clone:", prototype_clone)

Output 📊

Original: Prototype Number: 1001
Clone: Prototype Number: 1001

This example demonstrates the cloning of a prototype object with its internal state.

Business Logic Method 🧠

Extend the prototype pattern to include complex scenarios where prototypes might need to have deep copy functionality, which involves copying of objects containing other objects.

Testing 🧪

The test_prototype.py file includes tests to ensure that the Prototype pattern is correctly implemented, verifying that the cloned objects maintain the same state as the original without being the same instance.
