To decouple object creation from usage in Python, apply creational design patterns like Factory Method or Builder, which isolate construction behind standardized interfaces to reduce coupling and increase flexibility. This skill documents these patterns with structured Python examples.

Factory Method lets subclasses decide which concrete product to instantiate, while Abstract Factory provides an interface for creating families of related or dependent objects without specifying concrete classes. This skill provides structured problem and solution examples for both Python approaches.

Use the Prototype pattern when runtime type selection requires cloning existing objects, and use the Builder pattern to construct complex objects step by step. This skill articulates their intents, pros, cons, and trade-offs to guide your decision.

Implement a Singleton in Python by restricting instantiation to a single instance for centralized object lifecycle management. This skill provides concrete Python code blocks illustrating the Singleton pattern alongside other creational mechanisms.

Yes, the skill provides decision guidance on when to apply each creational pattern in library and framework design. It articulates pattern intents, pros, cons, and trade-offs with practical Python examples for scalable systems.
