def newfoo(arg1, arg2, *nkw, **kw):
    print 'arg1 is:', arg1
    print 'arg2 is:', arg2
    for eachNKW in nkw:
        print 'additional non-keyword arg:', eachNKW
    for eachKW in kw.keys():
        print "additional keyword arg '%s': %s" (eachKW, kw[eachKW])

10. 5. 4. Both keyword and non-keyword variable arguments may be used in the same function as long as the keyword dictionary is last
10. 5. 5. Calling Functions with Variable Argument Objects
10. 5. 6. ** works for keyword arguments: it collects them into a new dictionary,
10. 5. 7. A dictionary containing all keyword arguments whose keyword doesn't correspond to a formal parameter
