Using a conditional operator as the sole expression in the conditional
of an if statement is pretty bad style in any language.  My point about
it being red herring is that this is simply a general style issue in any
language, not just Python.  I suspect that its use will be very rare in
Python, just like it is in C, C++, Java, or Perl.
