[FIXED] Is there a pretty way to yield if in Python 3.3?

Issue

Is there a way to make this code prettier?

strong = li.find_all("strong")
if strong:
  yield li.find_all("strong")

I mean something like this:

strong = li.find_all("strong")
yield li.find_all("strong") if strong

Solution

You'd use:

strong = li.find_all("strong")
if strong:
    yield strong

instead of calling find_all() again (which, in BeautifulSoup, gives the same result but does the work again).

There is no 'conditional yield'. You could play tricks with yield from but I'd recommend against that.
