How do you copy an object in Python?

In Python, we use = operator to create a copy of an object. You may think that this creates a new object; it doesn’t. It only creates a new variable that shares the reference of the original object. Let’s take an example where we create a list named old_list and pass an object reference to new_list using = operator.
