How do i print out a number triangle in python using a loop based program? It is not a homework assignment or anything its just an exercise from the book i have been trying to do but have not really come close. The triangle should print out looking like this:

1
2 2
3 3 3
4 4 4 4
5 5 5 5 5
6 6 6 6 6 6
Answer

Just thought I would drop this here, even though it actually avoids using nested loops. But uses some elegant algebra.

for i in range(1, n):print((i*(10**i-1))//9)

In essence it is simply because 10^n-1 is n consecutive 9s. I will leave the rest up to you ;-)
