I think I now understand why I am getting this EOF exception.

Since the try/except is within a while loop, the input tries to read
more input after the ValueError occurs. Of course, I don't have any
more input strings stored in the StringIO buffer, so it sees this as
an end of file condition.
But now I do not see how to test get_input() to check for the
ValueError. Any suggestions?
