Well the message explains why you can't do this. `a` is bound to an
integer and integers are not iterable.

``len(a)`` wouldn't work either because integers have no "length":
In [16]: a = 1
In [17]: len(a)

Yes, don't try iterating over objects that are not iterable. ;-)
What you *can* do is iterating over lists, tuples or other iterables with
just one element in them. Try ``a = [1]``.
