Answer 1

n=  int(input('Enter integer here: '))
s = 2*n-1
a = 1
b = 1
for a in range(s+1):
    if a%2 != 0:
        val = (s - a) // 2
        print (". "*val + "0 "*(a) + ". "*val ,end = "\n")
for b in range(s-1,0,-1):
    if b%2 != 0:
        val2 = (s-b)//2
        print (". "*val2 + "0 "*(b) + ". "*val2 ,end = "\n")

Enter integer here: 5
