Forgive my ignorance of "*any" notation. I don't have real experience of
using it in my codes so far, and didn't know those parameters were
packed as a tuple:-(

The attached is a script which can run under Python 3.4/Windows Vista

how?
90% of the script you attached is irrelevant to your question. None of
the tkinter or threading code is important. The only important parts
are:
def threaded(action, args, context, onExit, onProgress):
def progress(*any):
threadQueue.put((onProgress, any + context))
Here we can tell that ``any`` is a tuple.
Oops, I misread your question. You thought any was an int. But the *
(star) notation in function parameters makes the parameter collect any
unnamed arguments into a single tuple.
def test(first, *args):
print(args)
test(1, 2, 3, "hello", 99)
=> prints the tuple (2, 3, "hello", 99)
