To clarify: When you say "to test", you mean the interactive
interpreter, right? If so, you need to end blocks of text with blank
lines (and not have any blank lines in between). It's because the
parser has to know when to run stuff; when you run a script, it parses
the whole thing and then runs it, but interactively, it has to work
piece-meal.
