Implement the Observer pattern in Python with a clean canonical class structure, type hints, and a runnable example. Also explain the responsibility of each role.

Runnable Observer pattern example code with role explanations and key implementation notes.

Analyze the following Python code and identify which GoF design patterns it uses. If any are present, point out the relevant classes, the evidence, and any implementation deviations.

A list of detected design patterns, relevant code locations, reasoning, and conformance assessment.

This Python code has many conditional branches and tightly coupled object creation. Determine whether it should be refactored into Factory Method, Strategy, or State, and provide the refactored code with migration notes.

Refactoring recommendations for the anti-pattern, the recommended design pattern, transformed code, and migration steps.
