Hi Everyone,
I feel there are still quite a few misconceptions around concerning

Recent discussion on the store vs. load syntax issues of PEP 622
prompted a (yet unripe) idea that could hopefully spur some progress.
What if cases required some sort of MatchCase (name pending) object
which could be preconstructed by the user if needed, but also inferred

programming and learn a bit more about computing. I was reading an article in
pc pro about creating a game using python so thought I would give it a shot.
However, when I try to execute on Geany I keep getting the sam
Hi Mohammad,
In addition to what Rhodri James has already well pointed out, here
are two additional thoughts on this.
At the moment, the keyword `global` is a marker to say that the
