Create a Diamond Pattern using For loop..

num = int(input())

for i in range(num-1): # to get diamond corners peak we have done num - 1 
        
    for j in range(i,num): # "space" decreasing triangle
        print(" " , end=" ")
        
    for j in range(i):     # " * " increasing triangle
        print("*" , end=" ")
    
    for j in range(i+1):  # " * " increasing triangle
        print("*" , end=" ")
    
    print()


for i in range(num):
        
    for j in range(i+1): #empty increasing triangle 
        print(" " , end=" ")
        
    for j in range(i, num-1): # " * " decreasing triangle & here in this line (num - 1) is for edge
        print("*" , end=" ")
    
    for j in range(i, num): # " * " decreasing triangle
        print("*" , end=" ")
    
    print()
