How to access the ith column of a NumPy multidimensional array?

.... Using the copied version is much faster: %timeit A_c1_ref.sum() # ~248 µs %timeit A_c1_copy.sum() # ~12.8 µs This is due to the different number of strides mentioned before: A_c1_ref.strides[0] # 40000 bytes A_c1_copy.strides[0] # 4 bytes Although it might seem that using column copies...
