Correct, I left out a bit, not wisely. I am trying to remember the last time (outside of classes) I have ever had to use bitwise operators nontrivially and it may have been around 1980 when I had to implement an encryption algorithm. Of course, when I was working in UNIX, I often had to combine bi

walrus with a twist :+= or ...

I realized that the person seeking completeness in Python may next ask why the Walrus operator, :=, is not properly extended to include a whole assortment of allowed assignment operators I mean in normal python programs you are allowed to abbreviate x = x + 5 with x += 5 Similar

Dave, You make me wonder about unintended side effects. Are we allowing the ++ and --- operations into Python through a side door? any context that allows you to insert the walrus operator like: index := index + 1 index := index - 1 Is now similar to notations in C/C++ and other
