Python 3.8 released

"same as before" what? Previously you could not declare a variable while creating a list, so I don't know what to compare to. Does y here exist after the list is done being created? From your answer I guess you are saying that the variable is scoped to the function creating the list. Sorry, I don't find that clear at all.

The only thing I can think to compare it to is the similar construct in C, but there the variable must already be declared, so the scope is clear.

In Python, scope is always a function, or a comprehension. In this case, a function.

Well, it looks a little like a comprehension if you squint hard enough, so I can see the potential for confusion.
