Print a numerical triangle [duplicate]

Question

You are given a positive integer (example: N = 6). Print a numerical triangle of height like the one below:

1
22
333
4444
55555 

Use no more than two lines of code. Use a for loop and print function only. You can't use anything related to strings. N is an input.

What I tried:

for i in range(1,int(input())):
    print(*range(1, i+1))

my output:

1
1 2
1 2 3
1 2 3 4

Answer 1

One way to get the triangle indicated (without using strings) is to treat the output as numbers and to calculate those numbers:

N = 6
for i in range(1, N):
    print(sum(10**j for j in range(i)) * i)

Output as requested.
