The strategy pattern is a type of behavioral pattern. See this,There's no reason to define a constructor if you aren't going to do anything, so just skip it.You don't really need this class at all.
Lets you define a family of algorithms, put each of them into a separate class, and make their objects interchangeable. The code I got is rather too simple, i.e. Strategy is a behavioral design pattern that turns a set of behaviors into objects and makes them interchangeable inside original context object. Different algorithms can be swapped in and out without any complications for the mentioned task.This pattern can be used to improve flexibility when external resources are accessed.The program shown below helps in implementing the strategy pattern.The above program generates the following output −.It provides a list of strategies from the functions, which execute the output.

You often need to implement Strategy, but Python simplifies this by allowing you to use a function without the overhead of a class wrapper around a function. One of the dominant strategies of object-oriented design is the "open-closed principle". All implemented behaviors are either classes, methods, or functions, and they are usually called.Strategy follows two important principles:Following these two principles is extremely useful when you want to design a common interface (the,In programming languages like Java you can implement the Strategy pattern by creating a common (abstract) interface and subclassing it with a new class for each strategy. We will learn what the strategy pattern is and then apply it to solve our problem. You can do the same in Python, like it’s done here.

In order to change the way the context performs its work, other objects may replace the currently linked strategy object with another one. This simplifies the "Strategy" Design pattern, as you don't need to create classes just for one method or behavior.
