What does the factory method do in Python?
Factory Method is a Creational Design Pattern that allows an interface or a class to create an object, but let subclasses decide which class or object to instantiate. Using the Factory method, we have the best ways to create an object.
Can you create an array of objects in Python?
You simply can’t do this; your second statement contradicts your first statement. You must instantiate as many objects as you wish to have, end of story. Even if you try to use some kind of copy function, it is just creating a new instance for you under the hood. What you can do is use a for loop to create your array.
What does abstract factory look like in Python?
The Abstract Factory pattern looks like the factory objects we’ve seen previously, with not one but several factory methods. Each of the factory methods creates a different kind of object.
When to change the factory in Python 3?
The factory ( ) is now the only other code in the system that needs to be changed when a new type of Shape is added (the initialization data for the objects will presumably come from somewhere outside the system, and not be a hard-coded array as in the above example).

Factory Method in Python. Factory method is a creational design pattern which solves the problem of creating product objects without specifying their concrete classes.
What should the factory method be used for?
Factory Method defines a method, which should be used for creating objects instead of direct constructor call ( new operator). Subclasses can override this method to change the class of objects that will be created.
How are functions used in a Python project?
Python functions are small, reusable blocks of code that you can utilize throughout a Python project. The standard Python library provides many useful built-in functions such as print () , len () , str () , int () but you can also define your own functions that can be used in your code.
Is the self parameter used in the factory method?
Because you started with some existing code, all the components of Factory Method are members of the same class SongSerializer. Usually, this is not the case and, as you can see, none of the added methods use the self parameter.
