The prototype pattern:
In order to implement the prototype design pattern, you basically take a partially constructed object
of indeed you can have a fully initialized object and you store it somewhere and then you deep copy the prototype whenever somebody wants to get an instance of it you allow the user to customize the resulting instance or if you are using a factory to provide a convenient API for actually using the protos in your code.


The idea is that you've already got an existing design and you want to name a copy of that design, customize it somehow and then start using it. All you need is copy.deepcopy

When it's easier to copy an existing object to fully initialize a new one.
