Mastering Python Design Patterns
By :

In software design, it’s easy to get caught up in the specifics of how a feature is implemented. However, focusing too much on implementation details can lead to code that is tightly coupled and difficult to modify. The principle of Program to Interfaces, Not Implementations offers a solution to this problem.
An interface defines a contract for classes, specifying a set of methods that must be implemented.
This principle encourages you to code against an interface rather than a concrete class. By doing so, you untie your code from the specific classes that provide the required behavior, making it easier to swap or extend implementations without affecting the rest of the system.
Programming to interfaces offers several benefits:
