Python 3000中的bool行为？ [英] bool behavior in Python 3000?

问题描述

有没有关于在Python 3000中使用真正的布尔值b / b
的讨论？说一句

类型''bool''数组的numpy实现？


希望修复bool类型将被修复，

我不确定我们现在所拥有的bool是不是真实的。

在数组的numpy实现中说出一些东西

$ b'类型''bool''？'


什么这方面你想要吗？ stdlib数组的bool typecode

模块？


我可以猜到你可能想要的一些东西，但最好是

如果您解释了当前行为的示例以及您希望它是什么

。

我见过的最后一个是

你是否愿意解释什么是破碎的？


彼得

最后我看到的是

好​​的。谢谢。

你是否愿意解释什么是坏的？

我想一个人要么发现算术运算的强制要求，要么是b / b或者不是。但这就是我的意思。


我的算术运算*，+， -

给出了标准解释两个元素

布尔代数：

与上面的链接相比，

it并不打扰我用int和bools算术

产生整数。


干杯，

Is there any discussion of having real booleans
in Python 3000? Say something along the line
of the numpy implementation for arrays of type ''bool''?

Hoping the bool type will be fixed will be fixed,

I''m not sure how the bools we have now are not "real."

Say something along the line of the numpy implementation for arrays

of type ''bool''?

What aspect of this do you want? A bool typecode for the stdlib array
module?

I can guess a number of things that you might mean, but it would be best
if you explained with an example of what current behavior is and what
you would like it to be.

The last I have seen is

Do you care to explain what is broken?

OK. Thanks.

Do you care to explain what is broken?

I suppose one either finds coercion of arithmetic operations to int
to be odd/broken or does not. But that''s all I meant.

My preference would be for the arithmetic operations *,+,-
to be given the standard interpretation for a two element
boolean algebra:
http://en.wikipedia.org/wiki/Two-ele...oolean_algebra

In contrast with the link above,
it does not bother me that arithmetic with ints and bools
produces ints.
