What is the result of the program?

❌ 5 5
❌ -5 5
✅ 5 -5
❌ -5 -5
❌ Error
❌ None of the mentioned

Explanation:
The slice expression on the right side of the assignment reverses the tuple. (y, x)[::-1] = (5, -5).
The assignment is thus equivalent to this compound tuple packing/unpacking assignment: x, y = (5, -5).
x and y retain the values they had originally.

Explanation:
The code line “second = first ” creates the shallow copy of the list. It means there will be a single list in memory. The first and second variables are pointed to the same list.
It does not maintain two separate lists, but only one. If you modify using one list variable, it will make the changes in the list for both variables.
If you want to maintain two separate lists for two list objects, you need to create a deep copy of the list.
