The Python list is very much the same concept as a to-do list or a grocery list. It is just a collection of values all in one variable. This list started of containing the numbers 1, 2, 3, and we just added a 4 to the end.

When you add an item to a grocery list, you don't take out a whole new piece of paper -- you just write on the same one. That is why the identity here behaves as it appears.

As an analogy, your own identity is who you are. You can change your appearance, by cutting your hair or changing what you wear, but you are still you. You can change your name, and you would still have the same identity.

(I think it is harder philosophical question what happens if you get a head transplant.)

Now let's take a look at these (again type or copy them separately)

p = [1,2,3] id(p) q = [1,2,3] id(q)

Group of answer choices

a) Each of these lists has a different identity

b) These have the same identity as each other

c) SyntaxError: multiple statements found while compiling a single statement

d) These have the same identity as the one given to x in the previous question

These have the same identity as the one given to x in the previous question
