从索引列表访问多维 np.array 的元素

Question

How can I access to the elements of a multi-dimension np.array given a list of indices? for example, I have a 2D np.array like arr= np.array([[10,20,30],[40,50,60]]) and a list of indices like list_ind = [(0,1), (1,1)] . The question is that how can I access to arr(list_ind), which is arr[0,1]=20 and arr[1,1]=50 ? Any idea?

Answer 1

simply:

arr[list_ind]

or yet better:

arr[tuple(list_ind)]

output:

array([20, 50])
