What is the difference between abstract classes and interfaces in Python?
In Python, abstract classes can have both abstract methods and concrete methods, while interfaces (using ABC) only define abstract methods.
Can you give me an example of each?
Sure! An abstract class can have a method with implementation, while an interface only declares methods without implementation.
When should I use an abstract class instead of an interface?
Use an abstract class when you want to provide a common base with shared code, and an interface when you want to enforce a contract without shared code.
Are there any limitations to using interfaces in Python?
Yes, interfaces in Python can't have any implementation, and you can't instantiate them directly.
