I'd always use i for loop variables I don't know what to call. It stands
for iterator or something. In a nested loop the next variable would
simply be called j and so on.
I also tend to use _, but in cases like:
_, _, something, _ = somecall()
where I only need one variable from a tupple. I only use this if I'm
sure the other values will probably never be of any use for the code.
However a large problem with _ is, that it is also the standard name of
the translate function of e.g. gettext.
In gui code you'll often find widget.setText(_("Save")). If you have
renamed _ this will give you problems.

I don't like dummy, as it is too long. I generelly spend more times
looking into long variable than short ones.
