There's also the else clause: Since is for comparing objects and since in Python 3+ every variable such as string interpret as an object, let's see what happened in above paragraphs. So for integers, ~x is equivalent to (-x) - 1. invert. This id is using in back-end of Python interpreter to compare two objects using is keyword.
