a : input array k : [int, optional, 0 by default] Diagonal we require; k>0 means diagonal above main diagonal or vice versa.
Lower triangle of a, having same shape and data-type as a.
Main Diagonal elements : [[ 1 0 0] [ 63 434 0] [ 54 54 56]] Diagonal above main Diagonal elements : [[ 1 21 0] [ 63 434 3] [ 54 54 56]] Main Diagonal elements : [[ 0 0 0] [63 0 0] [54 54 0]]
