[Numpy-discussion] array indexing problem

Hello, I am trying to extract a column from a 2D array here is what is have done: -------------------------------------------- In [3]: a = array([[1,2,3],[1,2,3]]) In [4]: a Out[4]: array([[1, 2, 3], [1, 2, 3]]) In [5]: a[:, 1] Out[5]: array([2, 2]) In [6]: a[:, 1:2] Out[6]: array([[2], [2]]) -------------------------------------------- when i use a[:, 1] i get a 1x2 array where as when i use a[:, 1:2] i get a 2x1 array. The intuitive behavior of a[:, 1] should be a 2x1 array. Am i doing something wrong here or is there some reason for this behavior ? regards, Rahul
