Concerning virtual threads the only problem
with Java I have is, that JDK 17 doesn't have them.
And some linux distributions are stuck with JDK 17.
Otherwise its not an idea that belongs solely
to Java, I think golang pioniered them with their
goroutines. I am planning to use them more heavily
Well you can use your Browser, since
JavaScript understand post and pre increment:
> x = 5
5
> x ++
5
> x = 5
5
> ++ x
6
So we have x ++ equals in Python:
x + = 1
x - 1
And ++ x equals in Python:
x += 1
x
But I don't know how to combine an
assignment and an expression into on
The wiked brain of ChatGPT gives me a lead:
PEP 659
Storing data caches before the bytecode.
Maybe its an effect of constant folding
and constant pooling by the compiler?

Hi,
In Java its possible to work this way
with the Integer datatype, just call
Integer.valueOf().
I am not sure whether CPython does the
same. Because it shows me the same behaviour

dress.

No, it's because integers in a certain small range are cached. Not sure
what the actual range is nowadays, it used to be some

Python 3.13.0a1 (tags/v3.13.0a1:ad056f0, Oct 13 2023, 09:51:17)
>>> x, y = 5, 4+1

You can try:
>>> 1,2 == 2,2
(1, True, 2)
Its the same as:
>>> 1, (2 == 2), 2
(1, True, 2)
Hope this helps!

Maybe consult:

There are three main types of awaitable objects:
coroutines, Tasks, and Futures.
