Python handles mutable and immutable objects in the same way.

Immutable objects are fundamentally expensive to “change”, because doing so involves creating a copy. Changing mutable objects is cheap. 

Immutable are quicker to access than mutable objects. 

Mutable data types are great to use when you need to change the size of the object. Immutable should be used when we need to ensure that the object will always stay the same.
