    I think it’s because not() is equivalent to not(None), and since None is falsy not(None) returns True.

      Are you sure?

      I can’t test it now, but to me it looks like () is an empty tuple. Python behavior is that for logic operations empty set equals to false. Then we apply not to get True. Not having space between not operator and parentheses makes it look like it is a function.

      Why is literally nothing equivalent to None? Is it because None is the default value of an optional parameter? (If so why oh why is it optional)
