Help me understand the meaning of the *not* keyword
def func(num): if num %2 == 0: return True else: return False print(not func(5)) The output I get is True. My question is just because it’s not 5 why doesn’t it mean it automatically is a 2 for the function to accept and return it as True. Can someone please explain the reason for this? An analogy would be: just because my son didn’t tell the whole truth doesn’t necessarily mean that he lied.

If this is in the python language (which is certainly looks to be), the not statement simply inverts, or negates, the state of a boolean. For example, if the value of a boolean variable or expression is true, it will result in false. If true, false is the result.
For example:
(True) and (not(False)) -> (True) and (True) -> true

True==not False
False == not True
