This is printing 1st row only and not slicing it to the given number of rows. Please help!

#define a function to print the matrix def matrix_print(matrix, x, y): #matrix_print(matrix, rows, columns) a = 0 for m in range(x): n=y print(matrix[a:n]) if n == y+1: a=y+1 n=y*2

cannot copy to code playground but at first glance it seems that you iterate only the colums in the first row. you do need two cycles nested.
