Ok...I got it.
Sorry for stupid question.

 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? If so, which 
 file(s) should I edit?

 I know C,C++ and Python programming and I am new to open-source 
 software development. Please help me.

 I have attached the screenshot with this mail.
