Does anyone know how I would go about conditionally raising an

I'm sorry about the typos, but that doesn't seem to be what the issue
is (I typed it into the textbox rather carelessly, I apologize :-( ).

If you're trying to return multiple values from a function, Python lets
you do that

... return x*2, y*2, z*2

>>> y = 2
>>> z = 3
>>> x, y, z = multiFoo(x, y, z)

Is the behavior below expected? Documented?
(The error msg is misleading.)

range is an iterator now. Try itertools.islice.
Well yes, it behaves like xrange did.
But (also like xrange) it supports indexing. (!)
So why not slicing?
I expected this (to keep it functionally
more similar to the old range).

Is this another lacuna or am I overlooking it?
I cannot find the 3.0 documentation of string

In Python 3, you can no longer ``exec(open(filename))``.
I guess the reason is that in 3.0 ``open`` returns a stream,
instead of open file, and exec wants
"a string, bytes, or code object" and not a "TextIOWrapper".
So it returns an error.
Is it intentional that ``exec`` cannot handle a TextIOWr
