AoC 2020 - Day 2: Password Philosophy

I am not very happy with the solution, but it worked at the first try.

This time I am using less ipython, and more python with type hinting. I am not sure if this is not removing the fun of the thing, or it’s just that I got used to it. But I also appreciate taking it a bit slower, and going in a simpler and steadier way.
