How do you write a program in python that creates pyramids based on user input? -

-

write program input height , outputs triangle of numbers given height:

  • each line should contain positive integer n​ denoting height of 1 triangle
  • inputting -1 should terminate value

  • output blank line after every test case

    sample input: 3 2 4 -1 sample output: 1 12 123  1 12  1 12 123 1234

this code 

inp = [] while true:     = int(input())     if == -1:         break     inp.append(i)  def pyramid(n):     return [list(range(1, i+1)) in range(1, n + 1)]  result = [pyramid(i) in inp] in result:     j in i:         print(j)     print('\n')
