I assume you're trying to remove the second instance of 2 without using pop(), because maybe you don't know the index in some hypothetical scenario.

I thought of something. It won't work on a list with three 2s though.

The print is calling for the sum of the list before it was altered.

The alteration has created a new object with a different ID.

The original ID is referenced by the last line of code.

Refer to attached code for details
