A class-based decorator is a class with a __call__ method that allows it to behave like a function. class UppercaseDecorator: def __init__(self, function): self.function = function def __call__(self, *args, **kwargs): result = self.function(*args, **kwargs) return result.upper...
A small tip, if you aim to lower your program's memory footprint: don't delete instance attributes, and make sure to initialize all attributes in your __init__!▶ Minor Ones *join() is a string operation instead of list operation. (sort of counter-intuitive at first usage) 💡 Expl...

It is automatically called when you create an object using a class; it is used to initialize the variables of the class. It is equivalent to a constructor. Like any other method, the init method starts with the keyword “def.” “self” is the first parameter in this method, just like...
