Паттерн Singleton (Одиночка) в Python

Singleton is a pattern for providing global access to state, guaranteeing that the object will always be the same. It's needed for a single point of access to resources/data and for executing resource-intensive tasks once. Monostate is a pattern for providing global access to state, but the objects can be different. Pros: We execute heavy tasks once, providing a single input for the entire system. Cons: A system-wide global variable. A module in Python is a singleton! That's why we can't escape them, even if we consider singletons an anti-pattern. 👉 Decorator with parameters    • Декоратор с параметрами   👍 The first decorator, understanding how to write it    • Первый декоратор, разбираемся с написанием   Read: https://www.oreilly.com/library/view/...
