Answer 1

num = int(input("Number of lines: "))
lterm = 1
rterm = num * num + 1
  
for i in range(num, -1, -1):
        
    for space in range(num, i-1, -1):
        print(" ", end ="")
  
    for j in range(1, i + 1): 
        print(str(lterm)+" ", end ="")
        lterm += 1
 
    for j in range(1, i + 1): 
        print(rterm, end ="")
        if j < i:
            print(" ", end ="")
        rterm += 1
        
    rterm = rterm - (i - 1) * 2 - 1 
    print()
