I can try to explain what I think it's happening: python interpreter
shell makes a consistent use of a prompt (either '>>> ' or '... ')
that makes commands indented by default by 4 chars. IDLE just presents
the '>>> ' for the first commands, and multiline instructions has to
be at the same level of indentation, and so the 'else' has to be at
the beginning of the line, since 'if' has no indentation.
