I understand "a if defined, else b" as
result = a
except (NameError, AttributeError, LookupError):
result = b
The problem is that None is not undefined. This is a regular value.
Seems it is not so special in Python as NULL or undef in other
languages. Python even don't have a special purposed
NullPointerException (or NoneError).
