Python ABC Module

Abstract base classes — ABC, abstractmethod, abstractproperty. This category documents 3 Python abc module entries, and each page gives you the full syntax, the parameter list, the return value, and a runnable example. The entries include: abc.ABC, abc.abstractmethod(), abc.abstractproperty(). abc.ABC a class that marks subclasses as abstract. Use with @abstractmethod to define interfaces. abc.abstractmethod() a decorator that marks a method as abstract (must be implemented by subclasses). abc.abstractproperty() defines an abstract property (deprecated, use @property + @abstractmethod instead). For a structured walkthrough of the whole topic, read the ABC Module guide. ABC Module belongs to the Core Language group alongside Built-in Functions, Statements & Keywords, Typing Module, Dataclasses Module. You can also search across every category from the search page, browse the complete A–Z index, or try any example in the Python playground. Python Reference documents 978+ functions, methods, and modules across 114 categories of the standard library, and every entry in this ABC Module category follows the same format — syntax first, then what it does, the parameters it accepts, what it returns, and a working code example — so once you have read one page you can read them all.
