Access to and editing of previous input lines is already provided by
the cooked mode of the console (e.g. on Windows, lean on the up-arrow
key) or can be obtained by installing the readline package. Perhaps by
analogy with _, you mean the *result* of the penultimate *expression*.
This functionality would be provided by the Python interactive
interpreter but it's not ... do have a look at IPython (http://; I don't use it but I get the impression
that if it doesn't already keep a stack or queue of recent results,
you could implement it yourself easily.
