An abstract class is a class that contains one or more abstract methods (a method that is declared but contains no implementation). Python on its own doesn't provide abstract classes. Yet, Python comes with a module which provides the infrastructure for defining Abstract Base Classes (ABCs). This module is called abc.

Example

To define an abstract class AbstractClassExample:

from abc import ABC, abstractmethod
class AbstractClassExample(ABC):
def __init__(self, value): self.value = value super().__init__()

@abstractmethod
def do_something(self):
pass

If the class that inherits this abstract base does not provide the concrete implementation of do_something, then we get an error.
