nonlocal is used to declare that a variable inside a nested function (function inside a function) is not local to it, meaning it lies in the outer inclosing function. If we need to modify the value of a non-local variable inside a nested function, then we must declare it with non...
The meaning of the syntax is similar to the function decorators. In the example above, you could’ve decorated the class by writing PlayingCard = dataclass(PlayingCard).A common use of class decorators is to be a simpler alternative to some use cases of metaclasses. In both cases, you’...
