Actually it has to do with what the helper function DIV expects / does with it's arguments... *arg expands a list, e.g. [a,b,c] and passes as 3 args; that is, it unpacks the list object;
Since python functions can also take keyword arguments (arguments whose position doesn't matter, and which a function definition may give a default value), then this: **kwarg expands dictionaries (think of them as associative arrays) into keywork argument pairs. A good way to read the '*list is "expand the list", and **dict as "expand the dictionary pairs (that is, the keyword:value pairs). See more here: http://www.network-theory.co.uk/docs/pytut/KeywordArguments.html http://www.network-theory.co.uk/docs/pytut/UnpackingArgumentLists.html http://www.network-theory.co.uk/docs/pytut/Dictionaries.html Hope that is helpful.
