Mutable and Immutable Objects are ways to categorize objects, into two different groups; one which couldn’t be modified, and the other which could be modified. Immutable is the objects which couldn’t be changed after it is created, and Mutable are the objects which could be altered after its creation. Immutable objects contain all the in-built types like int, float, tuple, etc., and Mutable consist of list, dict, set, etc. And a custom class generally falls under the Mutable objects group.
