Lawrence,
maybe it was not the perfect adjective. I meant 'not beautiful'
because for me it is not an expression I can easily read. It is not
internalized in my brain. I know how to use it because I learnt how to
do it time ago(in Learning Python) but always I have to think how it
works (like a mental translation). For me the other alternative
expresion is more readable:

take_it if you_have_it else search_for_it

this was already in my brain before I started writing python code.
Thus, I prefer this option for my code. On the other hand, in my post,
I proposed the and/or style because I found interesting how
symmetrical it was with the one the OP was refering:

(a==b)  ?  'Yes'  : 'No'
(a==b) and 'Yes' or 'No'


I know, I could write it without parenthesis but it seems more
naturally organized with it and I read it faster and clearly. I dont
know exactly why but it seems also safer to me.

Joaquin
