The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. The actual size of the integer types varies by implementation. The standard requires only size relations between the data types and minimum sizes for each data type: WebWhy `issubclass (int, int)` is true. As far as I am aware int shouldn't be a subclass of itself. This question applies to every other type in python, built-in or not, e.g. class C: pass issubclass (C, C) # True issubclass (str, str) # True.
