 def tri(n): #declaring function

    for i in range(n):     # i will be executed n times

        for j in range(i):  # j  will be executed i times

            print('*', end = ' ')  # printing star in straight line 

        print() # for going to next line  
  
tri(10) # argument passed as n = 10 


in third line j is executing i times that is , when the value of i = 1 , j will execute 1 time by printing a " * " ,and by print() statement the execution will go to next line and when i = 2 , j will execute 2 times by printing " * " 2 times
