I have an array like this:
import numpy as np
array=np.array([[3,2,1,17],[1,2,1,25],[1,2,2,-1],[1,1,5,105]])
[[ 3 2 1 17]
[ 1 2 1 25]
[ 1 2 2 -1]
[ 1 1 5 105]]
I want to sort it so that it looks like this:
[[1 1 5 105]
[1 2 1 25]
[1 2 2 -1]
[3 2 1 17]]
So basically I want to sort the order of the rows based on the first three values in each of them. Can someone point me in the right direction?
