a=[['2' '7' 'fas'] ['4' '8' 'sda'] ['1' '5' 'daf'] ['2' '24' 'gag']] how can matrix a, instead last "atribute" in each row:
a=[['2' '7'] ['4' '8'] ['1' '5' ] ['2' '24']] i know last element in row [:-1]
i tried numpy:
a[:, ?? ] matrix random elements, thinking somethin in way: a[:,end-1], numpy don't know end
>>> arr=np.array([[1,2,3],[4,5,6],[7,8,9]]) >>> arr[:,:-1] array([[1, 2], [4, 5], [7, 8]])
