If you start with the assumption that "intuitively obvious" doesn't
actually mean "intuitively obvious" but actually means something
completely different, then your statement definitely means something
non-contradictory. But if you start with the assumption that
"intuitively obvious" really does mean that the purpose and meaning of
for-else can be understood easily without external information, then
your statement contradicts itself.

This is comp.lang.python, not alt.english.remedial, so we expect you
to use English competently, or at least accept correction when you
misuse words.

Except that you haven't. Your proposed solution is incorrect and false.
