I have two arrays, for example:
我有两个数组，例如：
array1=numpy.array([1.1, 2.2, 3.3])
array2=numpy.array([1, 2, 3])
How can I find the difference between these two arrays in Python, to give:
如何在Python中找到这两个数组之间的区别，给出：
[0.1, 0.2, 0.3]
As an array as well?
作为阵列也是？
Sorry if this is an amateur question - but any help would be greatly appreciated!
对不起，如果这是一个业余问题 - 但任何帮助将不胜感激！

This is pretty simple with numpy, just subtract the arrays:
numpy非常简单，只需减去数组：
diffs = array1 - array2
I get:
我明白了：
diffs == array([ 0.1, 0.2, 0.3])

you can also use numpy.subtract
你也可以使用numpy.subtract
example:
例：
import numpy as np
array1 = np.array([1.1, 2.2, 3.3])
array2 = np.array([1, 2, 3])
print 'the difference =', np.subtract(array1, array2)
which gives you
给你的
the difference = array([0.1, 0.2, 0.3])
