Answer 1

rows = int(input("Enter the number of rows: "))  
  
k = 2 * rows - 2  
for i in range(0, rows):  
    for j in range(0, k):  
        print(end=" ")  
    k = k - 1  
    for j in range(1, i + 1):  
        print(j, end=" ")  
    print("")  
  


k = rows - 2  
for i in range(rows, -1, -1):  
    for j in range(k, 0, -1):  
        print(end=" ")  
    k = k + 1  
    for j in range(1, i + 1):  
        print(j, end=" ")  
    print("")
