翻转零和一在一维numpy的阵列 [英] Flipping zeroes and ones in one-dimensional NumPy array

问题描述

我有一个一维数组numpy的，由零和一像这样的：

I have a one-dimensional NumPy array that consists of zeroes and ones like so:

array([0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1])

我想一个快速的方法只是翻转的值，使得零成为的人，那些和零变，导致numpy的数组是这样的：

I'd like a quick way to just "flip" the values such that zeroes become ones, and ones become zeroes, resulting in a NumPy array like this:

array([1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0])

有一个简单的单行这个？我看了看 fliplr（）的功能，但是这似乎需要的尺寸大于或等于2的numpy的阵列。我敢肯定有一个相当简单的答案，但任何帮助，将AP preciated。

Is there an easy one-liner for this? I looked at the fliplr() function, but this seems to require NumPy arrays of dimensions two or greater. I'm sure there's a fairly simple answer, but any help would be appreciated.

推荐答案

一定有什么东西在您的问与答，我不明白...

There must be something in your Q that i do not understand...

反正

In [2]: from numpy import array

In [3]: a = array((1,0,0,1,1,0,0))

In [4]: b = 1-a

In [5]: print a ; print b
[1 0 0 1 1 0 0]
[0 1 1 0 0 1 1]

In [6]:
