How do you copy an object in Python?

In Python, the assignment operator (=) creates a reference between the target variable and the object, rather than creating a new copy of the object. To create a copy of an object, you can use the copy module.

There are two types of copies that can be created using this module: shallow copy and deep copy. A shallow copy creates a new object with a copy of the values in the original object, but if the original object contains references to other objects, the shallow copy will only copy the references. A deep copy, on the other hand, creates a completely new copy of the original object, including any referenced objects.


Shallow copy

Here is an example of how to use the copy() function to create a copy of a list object:

Deep copy

You can also use the deepcopy() function to create a deep copy of an object, which copies not only the object itself, but also any objects it contains (if it is a container object).
