Answer 1

You can read about the Pascal triangle here:
https://en.m.wikipedia.org/wiki/Pascal%27s_triangle

1
1 1
1 2 1
1 3 3 1
1 4 6 4 1

The code prints consecutive powers of 11 which happen to be consecutive Pascal's triangle rows, digit-wise -- 11, 121, 1331, 14641...

Answering your question -- no, it's not Python-specific, you can do that in any other language, too. The power operator (**) might be different or non-existent (you have to use pow() in C++), but the mechanism is the same.

Answer 2

Yes, or simply put 11**n

Answer 3

i understand... it is (10 + 1)**n
right?
