Use the @property decorator to encapsulate data, allowing you to add validation or transformation logic later without breaking the public API.

class Singleton: _instance = None def __new__(cls, *args, **kwargs): if cls._instance is None: # Delegate memory allocation to the base object class cls._instance = super().__new__(cls) return cls._instance def __init__(self, value): # Warning: __init__ will still run every time Singleton() is called self.value = value Use code with caution. 2.
