when using __new__
we use it to override correct? just like with super, but what im unsure of is what exactly are we overriding? when super was introduced we would use super to override the method in the parent class for our code in the sub class but so what are we using __new__
to override? is it the fact that were dealing with str and they're immutable?

method that creates and returns the new instance. It is the __new__
method that calls __init__
to initialize the instance. This is why the __init__
method does not return an object. It is the self
referenced in the __init__
that is returned by the __new__
method.
The ___new__
method is overridden when extending an immutable type to allow changing the object creation arguments before it is created. super()
is then used to call the parent’s __new__
method to create the instance.
On terminology, super()
doesn’t override the parent method, but rather executes the parent’s method from with the overriding child method.
Post back if you need more help. Good luck!!!
