Well, as the preceding line said in the original:

>>    "if key:value in dict"]:

I think you've guessed which 2/3 those are <wink>.  I don't see that the
last line has any visible semantics whatsoever, so Python can do whatever it
likes, provided it doesn't do anything visible.

You still hang out on c.l.py!  So you gotta know that if something of the
form

    x:y

is suggested, people will line up to suggest meanings for the 3 obvious
variations, along with

    x::y

and

    x:-:y

and

    x lambda y

too <0.9 wink>.
