sure! in python, when you need to make a copy of an object, you can use the `copy` module which provides two main functions for copying objects: `deepcopy` and `copy` (shallow copy).

*shallow copy:*
a shallow copy creates a new object but does not create copies of nested objects. this means that changes made to the original object may affect the copied object and vice versa.

here is an example of shallow copy:



output:


*deep copy:*
a deep copy creates a new object and recursively creates copies of nested objects. this means that changes made to the original object will not affect the copied object.

here is an example of deep copy:



output:


as you can see in the examples above, shallow copy retains references to the nested objects, while deep copy creates separate copies of the nested objects.

make sure to choose between shallow copy and deep copy based on your requirements to avoid unexpected behavior in your code.
