Chess Board

Given two numbers n and m. Create a two-dimensional array of size (n×m)and populate it with the characters "." and "*" in a checkerboard pattern. The top left corner should have the character "." 



above figure shows the main chess board pattern, note that "." means white and "*" means black

	n,m = map(int,input().split())
	b=[['. ' for x in range(m)]for y in range(n)]
	for i in range(n):
	for j in range(m):
	if(i%2==0 and j%2!=0):
	b[i][j]='* '
	elif(i%2!=0 and j%2==0):
	b[i][j]='* '
	for i in range(n):
	for j in range(m):
	print(b[i][j],end="")
	print('\n')
