I believe this is a historic idiom from back before the ternary operator 
was added to Python:

   x = x if x else 'some other value'

though honestly both of those are poor ways of spelling

   if not x:
      x = 'some other value'

It really isn't, particularly not in Python

I don't find the combination of letters and symbols appealing, sorry.
