not() is a base function that negates what’s inside (turning True to False and vice versa) giving it no parameter returns “True” (because no parameter counts as False)
Actually, not
is an operator. It makes more sense if you write not()
as not ()
- the ()
is an empty tuple. An empty tuple is falsy in Python, so not ()
evaluates to True
.
