You are confusing two different things..
The first case is that of inte

Hi,
let X be a mutable container, such as dict/set/list=bytearray, and Y=X,
When I change X, Y will follow it, having always the same value, although
id(X)!=id(Y). How is that, what is the explanation? Meanwhile the same for
immutable types results a real copy, and so does for simple mutables such

Actually, no, this case it's not your ignorance. What is probably
going on is that you are using Python 2, but the book is going with
Python 3.
You can quickly check the version by just typing python at
an OS command prompt to get into the interactive interpreter(>>>)

You are slightly confused - ints are not mutable! You can combine or
multiply them, along with several other operations, but they are certainly
not mutable. The easiest way to check is use them as keys in a dict. You

All right, I was really wrong in this question (here it is after midnight

Walter and Dave, thank you for the useful and detailed answer, now I see it
better. I didn't write code, because once I realized I had spoiled
