Right... because you don't have anything to increment or append to. I
guess this also comes up in the case of something like lists or
dictionaries you want to uniformly create in a loop. I guess you
could call it instantiating, but really it's more like going ahead and
assigning to them as Chris mentioned and you're just starting them
with a default value. Assuming you're working with strings, x=""
should work just fine in that case. Lists, x=[], dictionaries, x={},
integers, probably x=1 or x=0...
