Code Explanation:
The copy method:
a.copy() creates a shallow copy of the list a.
A shallow copy means that a new list object is created, but the elements inside the list (if mutable) are not deeply copied.
The is operator:
is checks for object identity, i.e., whether two variables refer to the same object in memory.
What happens here:
a and b are two distinct list objects in memory because a.copy() created a new list.
Even though the contents of the two lists are the same, they are not the same object.
Verification:
print(a == b) would return True because == checks for value equality, and both lists contain the same elements.
print(a is b) returns False because they are two different objects in memory.
