The great thing about Python is that this actually runs

I don't get it, why shouldn't it run?

@odietamo Because of the '...' (it's literally in the code).

@LevitatingLion hahahahah didn't know that

Well python is interpreted, is it not?

I guess it does not parse parts that are unreachable.

Have seen the same in other languages. Lines are parsed on a need to basis and this script never reaches the dots.

@Voxera It reaches the dots every iteration of the while-loop, but the three dots are a valid Python expression (the Ellipsis object) and thus no error is raised.
As far as I know, Python gets "compiled" into some sort of byte code before execution (like Java); It's not interpreted as-is like it's the case with Perl.

@LevitatingLion ok :)

I did not know about that, never really used python except for some experimentation.
