Boštjan Mejak added the comment: My hat off to you, Mr. Peters! Your suggestion (len(moves) + 1) // 2 works perfectly and is much more elegant than --0-- len(moves) // 2. :) Mr. Stinner, in what way would int.bit_count() be beneficial to me? -- ___

Boštjan Mejak added the comment: The spaceship operator is kinda cool! :) Well, I was hoping to avoid importing the math module just to have ceil division capabilities. Anyway, my need for ceiling is that I am coding a chess GUI where I have a table with 2 columns and I create a new row when

Mark Dickinson added the comment: I can't recall where I saw this originally, but you can use the spaceship operator "--0--" to turn floor division into ceiling division: >>> 12//5 2 >>> --0-- 12//5 3 There's also the ++0++ operator when you want to emphasize that you really *do* mean floor

[issue43255] Ceil division with /// operator

STINNER Victor added the comment: I'm not convinced that this operation is so common that it deserves a new operator. As Serhiy wrote, it must be first on python-ideas first. I close the issue. -- floor division is x//y integer ceil division can be implemented with math.ceil(x/y) for small

Serhiy Storchaka added the comment: Since adding new operator is a syntax-level change, it needs a PEP. It is better to start with discussing on the Python-ideas mailing list (https://mail.python.org/mailman3/lists/python-ideas.python.org/). Let's see if this idea will be accepted favorably.

New submission from Boštjan Mejak : I hope I'm not too late for a Python 3.10 feature request. I love the fact that Python 3.x does floor division with the // operator. We, however, don't have a ceil division operator, besides importing the math module and using its math.ceil() function. Is i
