Addition of a "plus-minus" binary numeric operator
Hi all, I was wondering on whether there is any interest in introducing a "plus-minus" operator: Conceptually very simple; instead of: upper, lower = a + b, a - b use instead: upper, lower = a +- b In recent projects I've been working on, I've been having to do the above "plus minus" a lot, and so it would simplify/clean-up/reduce error potential cases where I'm writing the results explicitly. It isn't a big thing, but seems like a clean solution, that also takes advantage of python's inherent ability to return and assign tuples.
May I ask what you are actually doing with upper and lower after creating them? Are you checking to see if another value is between? Something else? If they are always being used together and you're doing the same things with them all the time, it starts to smell like you might want to just write a class. --- Ricky.

Hi Yahbai You might wish to reconsider your proposal in light of existing behaviour

Consider also your proposed
a, b = 2 +- 1 We know that {a, b} = {1, 3}. But which is which?
In your use case you might be better off introducing a custom type
I hope this helps you with your code. best wishes Jonathan
