[英]Searching a Numpy Array for the index of a subarray based on a subarray of the subarray
[英]Get a subarray from a numpy array based on index
我有一個numpy數組向量,我想得到一個基於索引的子集:
import numpy as np
input=np.array([1,2,3,4,5,6,7,8,9,10])
index=np.array([0,1,0,0,0,0,1,0,0,1])
什么是pythonic方法來輸出輸出= [2,7,10]?
output = input[index.astype(np.bool)]
要么
output = input[np.where(index)[0]]
