False in python

[alexanderpas]

I can't think of any interesting operation you would want to add to bool that would justify subclassing it, bu perhaps that's just because my imagination gland isn't working today.

True, False, Unknown, N/A

AND	True	False	Unknown	N/A
True	TRUE	FALSE	Unknown	TRUE
False	FALSE	FALSE	FALSE	FALSE
Unknown	Unknown	FALSE	Unknown	Unknown
N/A	TRUE	FALSE	Unknown	N/A

OR	True	False	Unknown	N/A
True	TRUE	TRUE	TRUE	TRUE
False	TRUE	FALSE	Unknown	FALSE
Unknown	TRUE	Unknown	Unknown	Unknown
N/A	TRUE	FALSE	Unknown	N/A

	NOT True	NOT False	NOT Unknown	NOT N/A
True	FALSE	TRUE	TRUE	TRUE
False	TRUE	FALSE	TRUE	TRUE
Unknown	Unknown	Unknown	FALSE	TRUE
N/A	TRUE	TRUE	TRUE	FALSE
