>import numpy as np
a = np.array([[1,2,3],[4,5,6],[7,8,9]])
a[0][:]
a[:][0]
Now both a[:][0] and a[0][:] are outputting the same result, i.e
np.array([1,2,3]). If I want to extract the array [[1],[4],[7]] then
what should I do? Is it possible to add this feature?
The feature is already there:
a[:, 0]
