Actually it would be

    result.extend(item)

But if that bothers you, you could consider the expansion
to be

result = []
for item in iterable:
    for item1 in item:
       result.append(item)

In other words, the * is shorthand for an extra level
of looping.

Not sure what you mean by that. It seems closely
analogous to the use of * in a function call to
me.
