I agree.
copy.deepcopy works for arbitrary objects and custom classes.
And if we would want to customise that - we can define __deepcopy__ method (or .clone() just to make it as GoF describes)

Also couple of interesting thoughts here:
https://python-patterns.guide/gang-of-four/prototype/#the-prototype-pattern

I also agree. Feel free to add a pull request that replaces the current code with a deepcopy example

@faif in any case, shouldn't the existing example be using copy.deepcopy() in the clone method?

@crypdick If there are no behaviour differences yes
