The diagonal parallel to the main

Statement

Given an integer n$n$, produce a two-dimensional array of size (n×n)and complete it according to the following rules, and print with a single space between characters:

• On the main diagonal write 0 .
• On the diagonals adjacent to the main, write 1 .
• On the next adjacent diagonals write 2 and so forth.

Print the elements of the resulting array.

n=7

0 1 2 3 4 5 6 1 0 1 2 3 4 5 2 1 0 1 2 3 4 3 2 1 0 1 2 3 4 3 2 1 0 1 2 5 4 3 2 1 0 1 6 5 4 3 2 1 0

	n= int(input())
	b=[[abs(x-y) for x in range(n)]for y in range(n)]
	for i in range(n):
	for j in range(n):
	print(b[i][j],end=" ")
	print('\n')
