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 Similarly you have other operators like x *= 2 And, of course, the constantly used operator: x %= 2 So how does one extend a walrus operator if they ever decide to give in and add it to the language just for completeness? Sadly, a simple test shows they neglected to use a :+= operator in the latest: >>> (walrus := 2) 2 >>> walrus 2 >>> (wallrus :+= 2) File "<stdin>", line 1 (wallrus :+= 2) ^ SyntaxError: invalid syntax (Yes, I know how to spell walrus, but making a point.) On a serious note, if it was ever considered a good idea, what would be an acceptable sequence of symbols that might not break or confuse existing programs and what would we call it? I mean what animal, of course. What do these look like in some fonts? :+= :-= :*= :/= :%= Or do we not just add a colon in front and make it a tad different as in :=+ or :+=: or maybe realize the futility of perfection! After all, you can easily use some functions to get a result such as: x := func(x, "+", 5) x := func_add(x, 5) or many other work-arounds. Can we all forget I asked? I am sort of being sarcastic. -- https://mail.python.org/mailman/listinfo/python-list
