为什么整数除法产生一个浮点数而不是另一个整数? [英] Why does integer division yield a float instead of another integer?

问题描述

Python 3.1 (r31:73574, Jun 26 2009, 20:21:35) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> 2/2
1.0

这是故意的吗?我强烈记得返回 int/int=int 的早期版本?我该怎么办，是否有新的除法运算符，还是必须始终强制转换?

Is this intended? I strongly remember earlier versions returning int/int=int? What should I do, is there a new division operator or must I always cast?

推荐答案

看一看 PEP-238:更改除法运算符

Take a look at PEP-238: Changing the Division Operator

//操作员将可以明确地请求楼层划分.

The // operator will be available to request floor division unambiguously.
