No. An interactive session is your friend. You can concatenate all sorts
of things, not just strings:

>>> [2, 3, 4] + [5]
[2, 3, 4, 5]
>>> (2, 3, 4,) + (5,)
(2, 3, 4, 5)

What should 4 + "5" give you? 9 or "45"?

Your description of the problem was *utterly* wrong. You said you get an
error when you try to print LatInt; but that's not true, is it? print
LatInt works fine, I bet. If you had actually posted the traceback, rather
than trying to describe it in your own words, your problem would have been
solved after one post. In other words, you sent us all on a wild goose

But the main thing is, the traceback was telling you exactly what was
wrong. Listen to it, it knows.
