import poser

scene = poser.Scene()

def get_document(scene):

    return scene.DocumentPath() if not scene.DocumentPath() is None else "Untitled"

document=get_document(scene)

Sorry for the " lecturer mode": but this is a good example of when you achieve a degradation with supposed code optimizations.

The function that returns the result is always called twice. Just to save one line of code.

The better (and more readable) way:

def get_document(scene):
  d = scene.DocumentPath()
  return d if d else "Untitled"

(In the end it's even less typed keys :))

---

Ok, i missed that scene.DocunebtPath() can return None.

The last line should be:

  return d if d is not None and d else "Untitled"

---

A test for None should always look like this:
  <statement> is None
or
  <statement> is not None.

But not:
  not <statement> is None

Why?

Once, because it is recommended by the Python documentation :).

And if you think about it, you will see that from <statement> the value is evaluated and then negated. The result is then checked for None (== None). If you write it correctly, the parameter is directly checked for != None. Which is of course more effective, and depending on what is behind <statement>, possibly also much faster.
