Delegation
Delegation is another technique that you can use as an alternative to inheritance. With delegation, you can model can-do relationships, where an object hands a task over to another object, which takes care of executing the task. Note that the delegated object can exist independently from the delegator.
You can use delegation to achieve code reuse, separation of concerns, and modularity. For example, say that you want to create a stack data structure. You think of taking advantage of Python’s list as a quick way to store and manipulate the underlying data.
