I have numpy array like this, where I have one column and one row of ZEROS :

 ([[0. , 2.8, 3.5, 0. , 2.5, 1. , 0.8],
   [0. , 0. , 0. , 0. , 0. , 0. , 0. ],
   [3.5, 2.5, 0. , 0. , 2.8, 1.3, 1.1],
   [3.6, 3.8, 3.3, 0. , 2.5, 0.6, 0.4],
   [2.5, 1.5, 2.8, 0. , 0. , 3.1, 1.9],
   [1. , 0.8, 1.3, 0. , 3.1, 0. , 2.8],
   [0.8, 1.6, 1.1, 0. , 1.9, 2.8, 0. ]])

I want to shift the zero-row to the top and the zero-column either to the left or remove it :

 ([[0. , 0. , 0. , 0. , 0. , 0. ]
   [0. , 2.8, 3.5, 2.5, 1. , 0.8],
   [3.5, 2.5, 0. , 2.8, 1.3, 1.1],
   [3.6, 3.8, 3.3, 2.5, 0.6, 0.4],
   [2.5, 1.5, 2.8, 0. , 3.1, 1.9],
   [1. , 0.8, 1.3, 3.1, 0. , 2.8],
   [0.8, 1.6, 1.1, 1.9, 2.8, 0. ]])

any quick and easy way to do it ? BTW I know the col&row-number, so i doesnt have to search for it.
